Detailed Description

This class contains the combination of a local plasticity model for concrete with a local isotropic damage model.

This is an extension of concretedpm2. The yield surface of the plasticity model is based on the extension of the Menetrey and Willam yield criterion. The flow rule is nonassociated. The evolution laws of the hardening variables depend on the stress state. The plasticity model describes only hardening and perfect plasticity. It is based on the effective stress. The damage parameter of the isotropic damage model is based on the total volumetric strain. An exponential softening law is implemented.

Method for computing 1d stiffness matrix of receiver.

Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to 1d stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix.

Parameters

mmode	Material response mode.
gp	Integration point, which load history is used.
tStep	Time step (most models are able to respond only when tStep is current time step).
