Detailed Description

template<int sizeMaterialState>
class Marmot::NumericalAlgorithms::PerezFougetSubstepperTime< sizeMaterialState >

Modified Version of the Perez-Fouget Substepper, to account for time-variant elastic Stiffness Tensor Cel(t_n+1) NO changes in algorithmic formulation!

modifications:

• elastic substep consistent tangent matrix update needs current Cel(t) for update
• No need for Cel for object construction anymore
