hypermesh中铝用什么材料卡片？

非常感谢！

谢谢！

在定义材料的时候，type里面有几个类型可以选择，分别是所有类型、各向异性、各向同性、流体和正交各向异性。在各向同性材料里有MAT1和MAT4，前者是定义线性各向同性的材料属性，后者是定义与温度有关的热材料属性，如电导率、热容、密度、动态粘度、热生成等等。不管是铝或者铝合金，他都属于线性各向同性的金属材料，选择MAT1，进入后填弹性模量，密度，泊松比等等就可以了。

mat1

中的截取，楼主可以参考，选取的铝的材料参数及卡片设置

Step 5: Define a material collector named aluminum for the bracket.

This material is defined for the channel.

1.	Right-click in the white space of the Model Browser.

2.	Select Create > Material.

The Create
material popup dialog appears.

3.	For Name: enter aluminum.

4.	Set Card image: to MAT1.

5.	Make sure Card edit material upon creation is selected.

6.	Click Create to create the material and edit it.

The card image for the new material appears.

7.	Click [E] and enter 7.0e4 in the field that appears.

This is Young’s Modulus.

8.	Click [NU] and enter 0.33 in the field that appears.

This is Poisson's Ratio.

9.	Click return to exit the panel.
