数值仿真分析中本构关系的介绍与设置(1)
1、1)Isotropic Elastic Model(各项同性材料):DENS(密度)、EX(弹性模量)、NUXY(泊松比),各向同性材料高碳钢的材料属性如下:

3、3)Anisotropic Elastic Model(各向同性材料):This material description requires the full elasticity matrix. Because of symmetry, only 21 constants are required. This material is only valid for SOLID164 and SOLID168 elements,for exampleCadmium:


5、5)Blatz-Ko Rubber Elastic Model(Blatz-Ko 橡胶弹性模型):这种超弹性模型,只需要定义材料的密度DENS、剪切弹性模量GXY:

7、7)Temperature Dependent Bilinear Isotropic Model(基于温度的双线性各向同性模型):For this material model, you must supply data over a temperature range wide enough to cover the actual temperatures that will occur in the analysis. Otherwise, the analysis will terminate.

9、9)Plastic Kinematic Model(塑性随动模型):Isotropic and kinematic contributions may be varied by adjusting the hardening parameter β between 0 (kinematic hardening only) and 1 (isotropic hardening only),1018钢材料的具体示例如下:

10、10)Piecewise Linear Plasticity Model(分段线性塑性模型):其需要输入的参数以及高碳钢材料的分段线性塑性模型,如下:
