◆ before_update()
template<class DataTypes >
|
inlineoverridevirtual |
This is called just before the material is updated on every points (usually just before a Newton step).
It can be used to update some coefficients that will be used on material points (for example, compute the parameters mu and lambda from the young modulus and poisson ratio given as data arguments).
Reimplemented from SofaCaribou::material::HyperelasticMaterial< DataTypes >.
◆ strain_energy_density()
template<class DataTypes >
|
inlineoverridevirtual |
Get the strain energy density Psi from the right Cauchy-Green strain tensor C.
Psi(C) = mu/2 (tr(C)-3) - mu ln(J) + lambda/2 (ln(J))^2
