Member Function Documentation

void sfem::material::MaterialType::createDefaultWrappers

(

const type_check_supported_strains &

wrapped_strains

)

creates default wrappers for all strain formulations given by 'wrapped_strains'. default wrappers are functions that wrap the corresponding strain formulation around the proper "xxxFEM" methods the function must be called AFTER all functors/internal data are set!

Parameters:

supported_strain

default value are all strains of this material

const index_type& sfem::material::MaterialType::getIndex

(

)

const [inline]

returns the specific integration point data

Parameters:

intpt

... number of intpt returns the material type

Member Data Documentation

Type_func_energy_n_stress_n_updateFEM sfem::material::MaterialType::func_get_energy_n_stress_n_updateFEM [protected]

a function computing the energy density and stress, and performing an update of the state variables, default: calls func_get_energy_n_stress and func_update_state_data; mode: symmetric strain tensor (in vector form)
