Detailed Description

template<int dim>
struct LinearElasticMaterial< dim >

Linear elastic material.

Defines a linear elastic material response. It satisfies the material_type interface for ElasticityOperator::SetMaterial.

Definition at line 25 of file linear_elastic.hpp.

Member Function Documentation

action_of_gradient()

template<int dim>

tensor< mfem::real_t, dim, dim > MFEM_HOST_DEVICE LinearElasticMaterial< dim >::action_of_gradient ( const tensor< mfem::real_t, dim, dim > & , const tensor< mfem::real_t, dim, dim > & ddudx ) const

inline

Apply the gradient of the stress.

Definition at line 46 of file linear_elastic.hpp.

gradient()

template<int dim>

tensor< mfem::real_t, dim, dim, dim, dim > MFEM_HOST_DEVICE LinearElasticMaterial< dim >::gradient ( tensor< mfem::real_t, dim, dim > ) const

inline

Compute the gradient.

This method is used in the ElasticityDiagonalPreconditioner type to compute the gradient matrix entries of the current quadrature point, instead of the action.

Returns

tensor<double, dim, dim, dim, dim>

Definition at line 62 of file linear_elastic.hpp.

stress()

template<int dim>

tensor< mfem::real_t, dim, dim > MFEM_HOST_DEVICE LinearElasticMaterial< dim >::stress ( const tensor< mfem::real_t, dim, dim > & dudx ) const

inline

Compute the stress response.

Parameters

[in]

dudx

derivative of the displacement

Returns

tensor<double, dim, dim>

Definition at line 34 of file linear_elastic.hpp.
