Hi Andrew, Yes, thats what i want, just simply put the elastic anisotropy at the Gauss point level. Thank you for the answer. Best, Ihsan On Tuesday, April 7, 2020 at 7:41:42 PM UTC+2, mac wrote: > > In the classical continuum approach to plasticity there is no grain > boundary. The

In the classical continuum approach to plasticity there is no grain boundary. The elastic anisotropy of the crystal is captured at the Gauss point level. So you would start by associating different materials properties (elastic / plastic) to Gauss points depending on their spatial location.

Hi Wolfgang, alright, suppose i have a box that divided into two regions, and each region has different elastic constant (anisotropy material). Perhaps the idea is when calculating the cell_matrix, inside the for-loop there is a function for choosing in which elastic constant to be used

Hi, Would anyone give me a hint on how to implement the polycrystal problem, i.e. more than one grain boundary? I already have the tensor mechanics solver written in deal.ii, but now it needs to be extended solveing also polycrystal problem. THank you. Best, ihsan -- The deal.II project
