abaqus与hypermesh接口教程

Consider a 96 in. x 12 in. cantilever beam as shown in the above figure. The beam is loaded at the right end by a force P = 40000 lb. The beam is isotropic with Young’s modulus E = 3x107psi and Poisson’s ratio ν= 0.3. Using Hypermesh and ABAQUS, perform the analysis outlined below. Start out by creating a relatively coarse mesh of 4-node quadrilateral elements (try a mesh of rectangular elements with 6 divisions in the x direction and 2 divisions in the y direction). Apply the appropriate boundary conditions, and run the problem assuming plane stress.Instructions for Lab#2Using Hypermesh and ABAQUS for the analysis of a beam in bending.Figure 1. Main Window in Hypermesh. Circled is the command toolbar that allows the user to access sub menus.Getting Acquainted1) Fire up Hypermesh from the menu controls.2) Familiarize yourself with the command toolbar to your right. By clicking next to eachtitle as circled above, you will be brought to several sub-menus where you may perform a variety of tasks. Click on each and analyze each sub-menu.3) Identify commands that appear self-explanatory, such as file, automesh, nodes,lines, ect....4) Notice that the file command exists in every toolbar.5) Click on the file command. This is where you name the hypermesh files you wouldlike to save using a *.hm extension. Also, this is where importing and exporting occurs.6) Also notice the template command. This is where the solvers are invoked.Hypermesh has the capability of exporting mesh information for a variety of solvers.Keep in mind, Hypermesh is purely a mesh generator and the mesh information must be translated into the format of the desired solver to be used, therefore picking the correct solver from the template is a necessary step before continuing with any other stepsGeometryIn this exercise we will generate the geometry of a beam to be deformed by applying a tip point load and by fixing one end. After completion of the geometry generation, a 3-dimensional mesh of the beam will be created and a stress analysis on the beam will be performed.1) Like all mesh generators, in order to create a mesh, some geometry must exist.Generally nodes are required from which lines are created. Surfaces must be created from a set of lines that form a closed loop. It is those surfaces that will be meshed.2) Click on the “Geom” icon to your right and notice the various menus. In particular,notice the “nodes” icon. Clicking on that will allow to create several nodes in a variety of modes. For example, by co-ordinates (most popular one), on lines, ect..3) Once the nodes exist, one can create lines from those nodes by clicking on the“line” button. Note the options available for the different type of lines that can be created. Go ahead and create lines from the existing nodes.4) With the lines created, surfaces can be generated by clicking on the “surface edit”button and by selecting the filler surface option. Create a surface using all existing lines.5) At this point the geometry has been created and mesh generation should be thenext step.Mesh generationIn this phase of the exercise the geometry created above will be meshed. The first step will be to mesh the two-dimensional surface with 2-D elements. Two meshes will be generated, a biased mesh and regular mesh. Samples can be seen in the figures below. When that is done, the two meshes will be extruded to create the three-dimensional brick element meshes.Figure 2. A simple quad mesh with no biasing.Figure 3. A biased quad mesh focused toward one end.Creating a 2-D mesh.1) With all surfaces created, it is time to mesh.2) Prior to creating elements, the concept of “collectors” must be reviewed.Hypermesh has the ability to store groups of elements under different names called collectors. In this manner, it is possible to modify parts of a mesh on a group basis.We will practice using these collectors to store the two meshes that will be generated for the same part. In one collector we will store the elements for the mesh in figure 2 and in another collector we will store the mesh for figure 3. To create collectors, click on the “collectors” button and create the two collectors using two different names and two different colors.3) You can toggle between the two collectors by using the “global button” in the righthand bottom corner and selecting the collector you wish to work in. It is important that you know which collector is being used as default and changing it will be necessary as the meshing progresses. Further you may display the desired collectors by using the “display” command in the bottom right corner and by clicking and un-clicking on each collector that is available. With that done we may proceed to create the two meshes.4) Make sure you know which collector is currently set to default. To begin meshing,click on the 2D toolbar to your right.5) There are a variety of options available. We will use the automesh option.6) By clicking on automesh, several parameters are required as well as the necessityto select the surfaces one wants to mesh.7) Select the surface by clicking on each and supply a rough idea of the element sizeand element type you would like to use. Also make sure you are in the interactive mode.8) Once that is done, clicking the mesh button will generate a tentative idea of howyour mesh will look along the geometry borders. You may enhance your mesh by improving on the coarseness, adding bias, ect... By clicking on the number of divisions for each line you may increase that value using the left button or decrease that value using the right button. Similar things can be done if one wants to change the bias or other parameters.9) With that done, clicking on the mesh button will create the mesh. Accept the meshby clicking return or reject it by clicking reject.10) T he above steps must be repeated to create a biased mesh toward the fixedlocation. To do that repeat steps 3-8, but ensuring yourself that you are in the appropriate collector. Also, when the tentative divisions on the border of your surface appear, you can add bias by clicking on the bias button and giving positive or negative bias values.Note: Your part may consist of several surfaces and you may mesh them all at once or separately. You may also allocate each meshed portion to different collectors, so as to be able to have control over your model based on the different portions meshed.Creating a 3-D mesh.1) The next step involves extruding the mesh from its 2-D version, thus creating a 3-Dmesh.2) The first step is two create two additional collectors into which the two 3-D mesheswill be saved.3) With that done, click on the “3D” button and click on the drag button.4) The drag button allows the user to drag a set of 2-dimensional elements into 3-dimensional elements so long that a drag direction and distance are supplied, as well as the intended number of divisions to be created on the way.5) Select the elements to be dragged by component and define a drag direction anddistance. Supply the intended number of divisions. With that done, click on the drag button. Your 3-dimensional mesh will be created within the chosen collector.6) Do the same for the second 2-dimensional mesh and ensure that it is put in theappropriate collector.7) With that done, it will be necessary to delete the unnecessary 2-dimensionalmeshes. To do so press the F2 key and delete elements by component and select the two components to be deleted. Click on “delete” to approve deletion of the two selected components.Boundary conditionsOnce the mesh has been created, it is necessary to create the required boundary conditions. Boundary conditions can be created within Hypermesh for use in ABAQUS, however the complexity of the steps within Hypermesh, outweighs the ease of typing in boundary conditions within the ABAQUS file, provided that the appropriate node sets and element sets are available. This is what will be done in the next steps.1) We need two sets. A node sets for those nodes that will be fixed and a node set forthose nodes onto which the load will be applied.2) To do so, click on the BCs menu. There you will create entity sets. Entity sets issimply a manner to groups nodes or elements under one common name. In ABAQUS, boundary conditions can be applied to those sets.3) Click on entity sets and create a node set called “fixed”. Select the nodes on the leftend of the beam by using the window select. When done click on create. If the set is created, click on RESET.4) Change the name to “load” and select the nodes onto which the load will be appliedand click on create.5) This will be it!With the mesh completed you may now export your file using the ABAQUS template and saving the file under a *.inp extension. You can do this by clicking on file and then selecting the export command. MAKE SURE YOU ARE USING THE “ABAQUS STANDARD” TEMPLATE. Be careful here!NOTE: Remember you have two meshes on top of each other. Before you export each mesh as *.inp file, you must create to separate Hypermesh files. In each file save only the mesh you desire. This is done by deleting the unwanted mesh and saving under a different name. Deleting elements or nodes is accomplished using the F2 command. It is also a good idea to go ahead and renumber your mesh when you are ready to finalize it. Renumbering is accomplished by clicking on the tools icon and then clicking on the renumber button. Do this for each mesh. Now we are ready for ABAQUS.IN ABAQUSThe general ABAQUS file follows your typical format for any FEA solver. It contains nodal information and connectivity as well as element type information. At the end are the boundary conditions and the solution procedure. This can be observed below.Open the *.inp file that was created. It should look as follows:**** ABAQUS Input Deck Generated by HyperMesh Version3.0**** Template: ABAQUS/STANDARD***** THIS IS THE NODAL INFORMATION*NODE1, 0.0 , 2.221825 , -7.778174: : :: : :: : :9843, 6.7033386359838, 3.648821000031 , 0.0539689803571*** THIS IS THE ELEMENT INFORMATION.

When that is done, you can run your two ABAQUS filesVIEWING THE RESULTS IN HYPERMESH.Once the ABAQUS run is complete, you need to convert the *.fil into a hypermesh *.res file. Do this by using the hmabaqus command within your unix template. Now open Hypermesh.1) Retrieve one of the models and click on the global button.2) You will see a path for the results file. Enter the filename assigned above.3) Exit this menu and click on the POST icon and view your results by using thecontour button.Some contour plots of a beam in bending. You may create displacement contours, stress contours, ect…Figure 4. The displacement contour plot for a beam in bending.Figure 5. Von-Mises Stress Contour for a beam in bending.General Tips:1) When meshing a model in separate portions it is necessary to create a collector foreach portion and making sure one has selected the correct collector before meshing a surface so that those elements created are fed into the desired collector2) Also, one must always check for duplicate elements or nodes. This can be donewith appropriate commands in the tools toolbar available at your right. We will explore these commands in class.。
