I am trying to simulate a 3D model in ANSYS workbench. The model is a carbon fiber resting on aluminium surface and a plunger which is displacing the carbon tow. I have created a symmetric model. I used solid elements and it works with no errors. What I need is a load vs Displacement graph plot. below is my model and my results. there is deviation from the experimental data. My hunch is that the material properties for my fiber are different from the experimental one.

Just for a reference this image is separately attached. The behavior of carbon fiber when ANSYS is run with BC's as similar to experiment. Please let me know why the deviation exists from the experimental data n

what material properties are being used here? are those linear or non linear? are large deflections on?n-AniketnHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn

The large deflections are on. Also I am using orthotropic material for my carbon fiber. Those are non-linear curves that i am trying to obtainn
