Hello,<\/p>\n

 <\/p>\n

I am trying to model a thin layer of a woven fabric. I am interested in simulating a tensile test to match experimental data. After a bit of research in the literature, I understood that the community uses an anisotropic Hyperelastic material model for these kinds of problems. I went to MCalibration and calibrated a material model based on the experimental data in the Warp and Weft directions and uploaded the material card in Ansys. I am using shell elements as the thickness of the layer is 0.36mm and with large deflection set to on. <\/p>\n

 <\/p>\n

I ran a transient simulation for a tensile test on a dogbone. The simulation failed to converge. I am attaching some of the settings I used. I tried applying a displacement BC and a velocity BC but it did not make any difference in the convergence. I tried to refine the mesh, I tried to reduce the time step, no success. I tried to simulate the problem with a normal hyperelastic (Ogden) material model from Ansys library, still I am failing to converge.<\/p>\n

I am attaching some photos that would help clarify the issues.<\/p>\n

 <\/p>\n

Could someone please guide me on what to do or what might be the problem?<\/p>\n
