Detailed Description

The class varelastisomat defines elastic isotropic material model with variable Young modulus and Poisson's ratio. These parameters are assumed to be calculated outside of this model, e.g. in the Cam-Clay model. Only initial values of Young modulus and Poisson's ratio are required to be specified in the input file. The current values are calculated by the calling of the mechmat give_actual_ym(ipp) and give_actual_nu(ipp) which are called with the default values of arguments and thus the specific calculation procedure implemented in the control advanced material model (e.g. plasticity) can be invoked.

Material parameters are:

initial Young's modulus (modulus of elasticity)
initial Poisson's ratio
