serac::solid_mechanics::NeoHookeanWithFieldDensity Struct Reference

Neo-Hookean material model This struct differs in style relative to the older materials as it needs to evaluate both stress and density. As a result, we want to clearly name these functions. This is likely going to be a new design going forward, at the moment it works with the SolidResidual class. More...

Neo-Hookean material model This struct differs in style relative to the older materials as it needs to evaluate both stress and density. As a result, we want to clearly name these functions. This is likely going to be a new design going forward, at the moment it works with the SolidResidual class.

SERAC_HOST_DEVICE auto serac::solid_mechanics::NeoHookeanWithFieldDensity::pkStress ( State &  , const tensor< T, dim, dim > &  du_dX, const Density &    ) const

inline

stress calculation for a NeoHookean material model

Template Parameters

T	type of float or dual in tensor
dim	Dimensionality of space

Parameters

du_dX

displacement gradient with respect to the reference configuration When applied to 2D displacement gradients, the stress is computed in plane strain, returning only the in-plane components.

Returns

The first Piola stress
