HyperMesh与Abaqus对比：接口分析实例[转载]

Hypermesh和Abaqus的接口分析实例(三维接触分析)

In this tutorial, you will learn how to:

ü Load the Abaqus user profile and model

ü Define the material and properties and assign them to a

component

ü View the *SOLID SECTION for solid elements

ü Define the *SPRING properties and create a component collector for

it

ü Create the *SPRING1 element

ü 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:

1.

From the Properties drop down menu,

select Card Edit.

2.

Click props and select

Solid_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 properties

In Abaqus contact problems, it is 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 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 card images are

listed.

5.

Click on card image= and select

SPRING.

6.

Click material=
