示例1: log
SquareMatrix<Scalar,Dim> NeoHookean<Scalar,Dim>::secondPiolaKirchhoffStress(const SquareMatrix<Scalar,Dim> &F) const
{
SquareMatrix<Scalar,Dim> identity = SquareMatrix<Scalar,Dim>::identityMatrix();
SquareMatrix<Scalar,Dim> inverse_c = (F.transpose()*F).inverse();
Scalar lnJ = log(F.determinant());
Scalar mu = this->mu_;
Scalar lambda = this->lambda_;
SquareMatrix<Scalar,Dim> S = mu*(identity-inverse_c)+lambda*lnJ*inverse_c;
return S;
}示例2:
SquareMatrix<Scalar,Dim> IsotropicLinearElasticity<Scalar,Dim>::cauchyStress(const SquareMatrix<Scalar,Dim> &F) const
{
Scalar J = F.determinant();
SquareMatrix<Scalar,Dim> stress = 1/J*firstPiolaKirchhoffStress(F)*F.transpose();
return stress;
