Youngs Modulus

Post by raven »

Hallo,

Is it possible to make the youngs modulus(matrix) for anisotropic materials depending on time or temperature?
e.g. for density it is clear
Density = Variable Temperature
MATC "1000*(1-1.0e-4*(tx-273))"
But how is it for a matrix?
Must I define an udf? And if so, how it looks?


Best regards, Rene
