However the I mm thickness we supplied will be carried as a numerical value into the selected analysismodule. Double click Engineering Data, cell B2 to view the Material Properties Data for Structural Steel, the default material that has been assigned to this part. To develop confidence in the process we start in Tutorial 4A by solving a simple structural static mechanical response problem. Keep this part in memory since we bave more work to do on it. Or it may be that a specific corner radius is required for the proper function of the part. Again, are there size changes that produce solid models? Click anywhere schematic to close the information box. Its not very big 70-75 pages.
Figure 2-16 Select the chamfer and hole. This Line-Body model can be expanded using the sketching methods described earlier to add more elements and dimensionality to the model. During manufacture of a real plate it would be difficult to make the edges of the hole meet with a zero radius at the corner. Compute the vertical deflection at the free end and the maximum bending stress at the top edge at the middle of the beam. Find the maximum values for von Mises stress, principal stress, shear stress, and displacement if the front and back surfaces have frictionless supports condition of plane strain and the interior has a pressure of7500 psi. Beam bending is supported by the creation of line models to which beam cross sections are attached.
You will not want to use this convergence process for problems you are very familiar with, but in certain cases it is a very useful tool. We follow the steps outlined above skipping those not needed in this tutorial. For example, Click on the Design Parameters Tab to edit the values shown. The features illustrated in Chapter I are sometimes called sketched features because they were based upon sketched cross sections we created. If you make a mistake, just delete the item in question and redraw, or just start over. Figure 3-2 Sketch and extrusion details. This demonstrates the m:nn~ 10 ful parts with the shapes desired base feature in order to create more complicate an use for specific tasks.
Define the allowable change in the maximum Normal Stress between solutions. Compare this result to the theoretical maximum stress in the plate without the added holes using tabulated stress concentration factors to determine the theoretical result. Set problem Parameters if desired. You need to get ansys workbench manual ,you can download it from torrent ,it contain bunch of examples and task to do so that you can get you hand on it 2. More space may be e at ' about '. Its dimensions are 1000 mm long, 400 mm high and 10 mm thick. Generate: Generate To create the surface.
Save your work and close the T4A Workbench Project. Figure 3-24 Generate Line Body. We'll use this line for angular reference. Edit anyone of the dimensions shown in these detail boxes then click Generate, and you see the part size change immediately. Figure 3-28 Close-up of section orientation. We can add features to base features to create more complex parts. This process starts the alternate solid modeler, loads that modeler's geometry to DeslgnModeler, and closes the alternate solid modeler.
It is usually most useful if the parameters are given names meaningful to the part. Also note that the tabulated displacement results show no change to three significant figures indicating that the displacements converge more rapidly than the stresses. Locate the line with an angular dimension. The previous results were all calculated using brick elements with midside nodes, giving 20 nodes per element. Figure 2-9 Selecting the blend option.
Throughout the text, readers are shown step-by-step detailed analyses for finite element equations development. A typical chapter consists of six sections. Tangent line and trim will be useful. I ProductView Express en iTunes ~ TurboTax 2011 ~ ·e. Many of these case studies are industrial or research projects that you build from scratch. We also discuss a list of tips and rules of thumb for applying the method in practice.
Selection Filter: Model Faces 3D 4. Sketch Visibility show Sketch Show Constraints? We get the results shown below. Specific topics covered include linear spring elements, bar elements, trusses, beams and frames, heat transfer, and structural dynamics. Some experimentation may be helpful. If the material is ductile and the loads are static, the high stresses at this location may not be of concern in the actual use of the part.
