I want to go to the deviator form, for this I need to fill in the elastic coefficient matrix. The matrix itself looks like this:
In one source I found information on determining elastic coefficients, but I'm not sure what to do exactly this way!
Also, ANSYS HELP says that the matrix must be positive definite and semmetric.
Also in ANSYS HELP says that the matrix can be either rigid or pliable.
How to determine the coefficients of elasticity for a rigid and flexible matrix?
