Hypermesh和Abaqus的接口分析实例

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 collector for it

✓Create the *SPRING1 element

✓Assign a property to the selected elements

Step 1: Load the Abaqus user profile and model

A 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, MADYMO, 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 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 properties

HyperMesh supports many different 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 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 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 changes to the card image.

12.Click return to exit the panel.

Step 3: Define the *SOLID SECTION properties

1. 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 sections 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 panel.

Step 4: Assign the property to the component

Because 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 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.

Step 5: View the *SOLID SECTION for solid elements

HyperMesh supports sectional properties for all elements from the property collector.

Complete the steps below to view the *SOLID SECTION card for an existing component:
