Detailed Description

template<class TPlasticPotentialType>
class Kratos::SimoJuYieldSurface< TPlasticPotentialType >

Short class definition.

This class defines a yield surface according to Simo-Ju theory.

Detail class definition.

The yield surface requires the definition of the following properties:

FRACTURE_ENERGY: A fracture energy-based function is used to describe strength degradation in post-peak regime
YOUNG_MODULUS: It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.
YIELD_STRESS: Yield stress is the amount of stress that an object needs to experience for it to be permanently deformed. Does not require to be defined simmetrically, one YIELD_STRESS_COMPRESSION and other YIELD_STRESS_TENSION can be defined for not symmetric cases
Template Parameters

TPlasticPotentialType The plastic potential considered
