Temperature dependent material model

M.Y

Hi all,

 

I am trying to create a transient heat transfer analysis with shell elements. The material in the model is steel and the following properties are temperature dependent: thermal conductivity, specific heat capacity, thermal deformation, elastic modulus and yield stress.

 

What would be the suitable RADIOSS material law? I know these properties could be easily created in Optistruct using cards MAT1, MATT1, MAT4 and MATT4, but I need to run my analysis on explicit solver.

Hi

You may take a look into LAW106
