1、Hypermesh与abaqus接口实例Hypermesh和Abaqus的接口分析实例（三维接触分析）In this tutorial, you will learn how to: Load the Abaqus user profile and model Define the material and properties and assign them to a component View the *SOLID SECTION for solid elements Define the *SPRING properties and create a component collect

2、or for it Create the *SPRING1 element Assign a property to the selected elementsStep 1: Load the Abaqus user profile and modelA set of standard user profiles is included in the HyperMesh installation. They include: RADIOSS (Bulk Data Format), RADIOSS (Block Format), Abaqus, Actran, ANSYS, LS-DYNA, M

3、ADYMO, Nastran, PAM-CRASH, PERMAS, and CFD. When the user profile is loaded, applicable utility menu are loaded, unused panels are removed, unneeded entities are disabled in the find, mask, card and reorder panels and specific adaptations related to the Abaqus solver are made. 1.From the Preferences

4、 drop down menu, click User Profiles.2.Select Abaqus as the profile name.3.Select Standard3D and click OK.4.From the File drop down menu, select Open or click the Open .hm file icon.5.Select the abaqus3_0tutorial.hm file.6.Click Open.Step 2: Define the material propertiesHyperMesh supports many diff

5、erent material models for Abaqus. In this example, you will create the basic *ELASTIC material model with no temperature variation. The material will then be assigned to the property, which is assigned to a component collector. Follow the steps below to create the *ELASTIC material model card:1.From

6、 the Materials drop down menu, select Create. 2.Click mat name = and enter STEEL.3. Click type= and select MATERIAL.4.Click card image = and choose ABAQUS_MATERIAL.5.Click create/edit. The card image for the new material opens.6.In the card image, select Elastic in the option list.7.By default, the

7、selected type is ISOTROPIC. If not, click the switch and select ISOTROPIC. 8.By default, the ELASTICDATACARDS= field value is 1. If not, input 1 to set the number of datalines.9.Click the field beneath E(1) and enter 2.1E5.10.Click the field beneath NU(1) and enter 0.3.11.Click return to accept the

8、changes to the card image.12.Click return to exit the panel.Step 3: Define the *SOLID SECTION properties1.From the Properties drop down menu, select Create. 2.Click prop name= and enter Solid_Prop.3.Choose a color for the property.4.Click on type= and set it to SOLID SECTION. This ensures that secti

9、ons pertaining only to solid elements are available as card image options. Alternatively, the type = field can be set to ALL ensuring that all available card images are listed.5.Click on card image= and select SOLIDSECTION.6.Click material= and select STEEL.7.Click create.8.Click return to exit the

10、panel.Step 4: Assign the property to the componentBecause the material is assigned to the property, when you assign the property to a component, the material is automatically assigned as well.1.From the Collectors drop down menu, select Edit and select Components. 2.Click the yellow comps button and

11、 select INDENTOR and BEAM from the list.3.Click select.4.If necessary, click the toggle to switch to property= . 5.Double-click property= and select the Solid_Prop.Notice that the card image= and material= are already set from the Solid_Prop property.6.Click update.7.Click return to exit the panel.S

12、tep 5: View the *SOLID SECTION for solid elementsHyperMesh supports sectional properties for all elements from the property collector. Complete the steps below to view the *SOLID SECTION card for an existing component:1.From the Properties drop down menu, select Card Edit.2.Click props and select So

13、lid_Prop from the list of property collectors.3.Click select to finish the selection process.4.Click edit to view the *SOLID SECTION property card image.5.Click return to finish the viewing process.6.Click return to exit the panel.Step 6: Define the *SPRING propertiesIn Abaqus contact problems, it i

14、s common to use weakly grounded springs to provide stability to the solution in the first loading step. This section explains how to create these springs and how to create the *SPRING card.Complete the steps below to create the *SPRING card:1.From the Properties drop down menu, select Create.2.Click

15、 prop name= and type in Spring_Prop.3.Choose a color for the property collector.4.Click on type= and set it to LINE SECTION. This ensures that sections pertaining only to 1D elements are available as card image options. Alternatively, the type = field can be set to ALL ensuring that all available ca

16、rd images are listed.5.Click on card image= and select SPRING.6.Click material= and select STEEL.7.Click create/edit.8.In the dof1 field, enter 3.The dof2 field in the *SPRING card is ignored by Abaqus for SPRING1 elements.9.In the Stiffness field, enter 1.0E-5.10.Click return to accept the changes

17、to the card image.11.Click return to exit the panel.Step 7: Create a component collector for the *SPRING property1.From the Collectors drop down menu, select Create and select Components. 2.Click comp name= and type in GROUNDED.3.Choose a color for the property collector.4.If necessary, click the to

18、ggle to switch to property= . 5.Double-click property= and select the Spring_Prop.Notice that the card image = and material = are already set from the Spring_Prop property.6.Click create.7.Click return to exit the panel.To reset the view for further processing:1.Click the isometric view icon .Step 8

19、: Create the SPRING1 element1.From the Mesh drop down menu, select Assign and select Element Type. 2.In the 1D sub-panel, click mass = and select SPRING1.In HyperMesh, grounded elements are created and stored as mass elements since they only have one node in the element connectivity.3.Click return t

20、o exit the panel.4.On the status bar at the bottom of the window, the name of the current component is displayed. Click on that name.5.Select GROUNDED from the list of component collectors that appears.As the spring elements are created, they will be placed in this component.6.From the Mesh drop dow

21、n menu, select Create and select Masses.7.Click nodes and select by id from the pop-up menu.8.In the id = field, enter 451t460b3 and click Enter on the keyboard.This shorthand selects all of the nodes from 451 to 460 in increments of 3.9.Click create. 10.Click return to exit the panel.定义接触面和相互作用Step
