chrono::fea::ChVoightTensor< Real > Class Template Reference
Description
template<class Real = double>
class chrono::fea::ChVoightTensor< Real >
Base class for stress and strain tensors, in compact Voight notation that is with 6 components in a column.
This saves some memory when compared to traditional 3D tensors with three rows and three columns, that are symmetric.
