Hello everyone
I am trying to use DAMASK to do the crystal plasiticty simulation. I faced one difficulty that the normal stress of each slip plane can not be obtained in DAMASK. I wanna if there is a solution to obtain the normal stress of each slip plane in DAMASK (maybe a little modification of existed code). Thanks a lot in advance.
Best regards.
Dear Yinfeng Cao many thanks for your interesting technical question. Personally I never worked in this area. However, please have a look at the following potentially useful articles which might help answering your question:
1. Computational Modeling of Dislocation Slip Mechanisms in Crystal Plasticity: A Short Review
and
2. Investigating the Interaction between Persistent Slip Bands and Surface Hard Coatings via Crystal Plasticity Simulations
Both articles have been published Open Access in the MDPI journal Crystals. Thus they can be freely downloaded as public full texts (see attached pdf files).

Dear Yinfeng Cao
if you need the stress on the slip planes as a postprocessing step, you would need to perform the following steps
1) output stress and orientation
2) input the plane normal of the considered slip systems (in cube orientation)
3) rotate the plane normals according to the crystallographic orientation and project the stress.
Dear Martin Diehl
Thank you very much for your very kind and useful help. I have succeeded in obtaining the normal stress of each slip plane. I am very glad to learn the crystal plasticity in DAMASK developed by your team. Thank you very much again.
