Dear All, I hope you have had a great time. I have a general question. I define total strain and deviatoric part of the elastic strain tensor in two different ways as below:
1- Total strain tensor: const SymmetricTensor<2, dim> total_strain = 0.5*(Grad_u + transpose(Grad_u)); (Tensor<2, dim> &Grad_u) const SymmetricTensor<2, dim> total_strain = symmetrize(Grad_u); 2-Deviatoric strain dev_T_elastic = deviator(T_elastic); dev_T_elastic = T_elastic - (1/dim) * trace(T_elastic) * (Tensor<2, dim>(StandardTensors<dim>::I))/3.0; It is interesting that I got two different results for each case. I would be very kind of you if you let me know what is the difference between each case of the two above section.
