base_tensor_type

template<int dim, typename Number>

using internal::SymmetricTensorAccessors::StorageType< 4, dim, Number >::base_tensor_type = Tensor<2, n_rank2_components, Number>

Declare the type in which we actually store the data. Symmetric rank-4 tensors are mappings between symmetric rank-2 tensors, so we can represent the data as a matrix if we represent the rank-2 tensors as vectors.

n_rank2_components

template<int dim, typename Number>

const unsigned int internal::SymmetricTensorAccessors::StorageType< 4, dim, Number >::n_rank2_components = (dim * dim + dim) / 2

static

Number of independent components of a symmetric tensor of rank 2. Since rank-4 tensors are mappings between such objects, we need this information.

Definition at line 450 of file symmetric_tensor.h.

n_independent_components

template<int dim, typename Number>

const unsigned int internal::SymmetricTensorAccessors::StorageType< 4, dim, Number >::n_independent_components

static

Initial value:

=
        (n_rank2_components *
         StorageType<2, dim, Number>::n_independent_components)

Number of independent components of a symmetric tensor of rank 4.
