Click OK on the warning window. Copyright DASSAULT SYSTEMES 6 ELFINI Structural Analysis Do It Yourself (2/3) Student Notes: Right click the “Property” node of the tree, select “Generate image” Choose “Thickness Fringe” Double click on the image itself or on the “Thickness fringe.1” node in the tree In the “Image Edition” panel, click the “more>>” button. Increase the “Lamina” field with up arrow See the different layers displayed Copyright DASSAULT SYSTEMES Perform the same operations with “Composite angle symbol” image Copyright DASSAULT SYSTEMES 7 ELFINI Structural Analysis Do It Yourself (3/3) Student Notes: Deactivate all images Apply Restraints In the “Restraints” toolbar, select the “clamp” Select the four border edges of the part Apply Pressure Apply a -10000N_m2 Pressure on the face of the part Copyright DASSAULT SYSTEMES Launch the computation Display displacement image Copyright DASSAULT SYSTEMES 8 ELFINI Structural Analysis Applying Mapping Property Recap Exercise Student Notes: This Exercise requires FMS License 30 min Copyright DASSAULT SYSTEMES In this exercise, you will learn how to apply Mapping Property, how to make changes in Mapping property file and re-applying mapping property after making minor geometric changes in part. Copyright DASSAULT SYSTEMES 9 ELFINI Structural Analysis Do It Yourself (1/4) Student Notes: Load Fuselage_Analysis.CATAnalysis Open Fuselage_Analysis.CATAnalysis Click on Mapping Property icon in Model Manager toolbar Select the part Copyright DASSAULT SYSTEMES Click on ‘Browse’ Button and select the supplied property file ‘Do_It_MappingProperty.xml’. Click ‘OK’ to confirm Compute ‘Mesh Only’ Copyright DASSAULT SYSTEMES 10 ELFINI Structural Analysis Do It Yourself (2/4) Student Notes: Go To ‘Generate Image’ in Property.1 contextual menu Create ‘Thickness Fringe’ Create ‘Physical Type Fringe’ image. Press ‘shift+ctrl’ and click element simultaneously to highlight element type. Copyright DASSAULT SYSTEMES Open Do_It_MappingProperty.xml file in notepad. Change the thickness of last three elements as shown in figure Change material of beam elements to User Material.2 Save the ‘Do_It_MappingProperty.xml’ file and close it Copyright DASSAULT SYSTEMES 11 ELFINI Structural Analysis Do It Yourself (3/4) Student Notes: Double click Mapping Property Click on ‘Synchronize file’ button Click OK to confirm Press ‘OK’ to update mesh Activate ‘Thickness Fringe’ Click OK in warning dialog box Click OK in Image Edition dialog box Copyright DASSAULT SYSTEMES Create ‘Material Fringe’ Copyright DASSAULT SYSTEMES 12 ELFINI Structural Analysis Do It Yourself (4/4) Student Notes: Double click the extrude surface. Again double click the extrude surface to get ‘Extruded surface Definition’ box. Change ‘Limit 1’ dimension = 70 mm Click OK to confirm Copyright DASSAULT SYSTEMES Double click ‘Mapping Property’ to return to Generative Structural Analysis Workbench Activate ‘Thickness Fringe’ Click ‘OK’ to update mesh Copyright DASSAULT SYSTEMES 13 ELFINI Structural Analysis Static Analysis with a Bearing Load Recap Exercise Student Notes: This Exercise requires KWA License 10 min Copyright DASSAULT SYSTEMES In this exercise, you will create a Bearing Load using a user-defined law profile type, and do static computation and post-processing. Copyright DASSAULT SYSTEMES 14 ELFINI Structural Analysis Do It Yourself (1/3) Student Notes: Load: BearingPart.CATPart Copyright DASSAULT SYSTEMES Open the GPS Workbench and create a new Static Analysis Clamp the bottom surface. Check the model consistency. Create a law type for the profile of the loading. Access the law editor. Create two formal parameters (angle and force). Enter : FormalForce.1 = cos(FormalAngle.1) Click OK, and select Law.1 in the tree in Bearing Load window. Copyright DASSAULT SYSTEMES 15 ELFINI Structural Analysis Student Notes: Do It Yourself (2/3) Apply a Bearing Load on the intern revolution surface of the part. Select the inner cylindrical surface as support. Choose a 500 N force along the Y axis. Choose an angle of 180 deg and a radial orientation (usual). Select the previously created law Choose « Outward orientation » Outward distribution Inward distribution Copyright DASSAULT SYSTEMES Load orientation can be either inward or outward Copyright DASSAULT SYSTEMES 16 ELFINI Structural Analysis Student Notes: Do It Yourself (3/3) Launch a static analysis. Visualize the displacements and Von Mises stresses. Copyright DASSAULT SYSTEMES The Bearing Load command allows to be closer to reality, with a no uniform loading only applied on a part of the surface. Use parabolic elements, 5 mm for size and 0.5 mm for sag. Copyright DASSAULT SYSTEMES 17 ELFINI Structural Analysis Combined Case and Buckling Analysis Student Notes: Recap Exercise 15 min In this exercise you will perform static analysis and buckling analysis of the hanger part. You will use: Copyright DASSAULT SYSTEMES Virtual Parts Combined case Buckling analysis Copyright DASSAULT SYSTEMES 18 ELFINI Structural Analysis Student Notes: Do It Yourself (1/4) Load: CATEST_Hanger.CATPart Clamps Apply clamps as shown. Apply Rigid Virtual Part to the inner surface of the hole as shown in the image. Apply 1000N Distributed Force along the y axis (global axis system). Select the Rigid virtual part as support. Visualize BC and load on mesh. Compute Static Case Solution. Visualize displacements and von Mises stresses. Use Layout to see them at the same time. What is the max displacement value ? Copyright DASSAULT SYSTEMES Force Copyright DASSAULT SYSTEMES Virtual part 19 ELFINI Structural Analysis Do It Yourself (2/4) Student Notes: Insert a new static case using the same restraints as previous static case. Apply the same load with new value : enter 5000 N. Compute. What is max displacement value ? Insert a new combined case. Double-click on the combined case. Select the first static case, and add the last one from the specification tree. Specify the coefficients : 2 and 1 respectively. Copyright DASSAULT SYSTEMES Compute the combined case. What is the max displacement value ? What about the two previous static cases ? Copyright DASSAULT SYSTEMES 20
