I have a question which seems quite simple but has troubled me for quite some time:
I have a composite tube modeled using layered solid elements C3D8, and I want to output radial, circumferential, and axial stress components averaged at preselected nodes (defined as a node set) in Abaqus data file (*.dat). Nevertheless, I would like to have those stress components expressed in a cylindrical coordinate system, rather than in local material coordinate system. I would appreciate it a lot if anyone knows whether it is possible to do so. Thanks.
