TPZPlasticState<REAL> TPZDruckerPrager::fInitialEps

private

variable to store the plastic state related to the unstressed state in a framework of a cohesion material. Since LadeKim models the cohesion material with the stress axis translated from a value of a, it is important to keep the related elastic deformation in this variable to subtract it from the epstotal answers. It is done because, intuitively, the initially nonstressed state should relate to an initially undeformed state.
