ComputeCosseratLinearElasticStress
Compute Cosserat stress and couple-stress elasticity for small strains
The Cosserat linear elastic stress tensor is computed from the Cosserat elasticity tensor, within the small strain approximation:
where
is the linear elastic stress tensor
the elasticity tensor (for example computed by ComputeCosseratElasticityTensor)
the strain tensor (for example computed by ComputeCosseratSmallStrain)
the coupled elastic stress tensor
the elastic flexural rigidity tensor
C the local curvature tensor (for example computed by ComputeCosseratSmallStrain)
The elastic strain is also computed to be the same as the mechanical strain, as there is no plasticity. The Jacobian, derivative of the stress with regards to strain, is simply set to the elasticity tensor, and the derivative of the coupled stress with regards to strain, is simply set to the elasticity flexural rigidity tensor.
This object is part of the Cosserat mechanics model. See the theory manual (at solid_mechanics/doc/theory/cosserat.pdf) for more explanation.
