Error:Non Asbestos Nitril Rubber Gasket Material
The model contains two gaskets sandwitched in between 3 different flanges. The preload 22 kN acts on 4 different bolts. The gasket has been simulated using solid 186 elements and 5 parameter Moony Revlin coefficients. The properties of the gasket are attached in the excel sheet provided. The solution is giving out high element distortion error in Ansys in the first substep.Can you please let me know if the attached material properties are correct.
Where did you get the material properties from?
Do you have experimental data?
I got the material properties from the supplier. The Excel file contains the experimental cuve fit data of the material.
I recommend that you try it with a Neo-Hookean material model first. The NH model is always stable so that is a good check to see if the problems that you mentioned are caused by an unstable material model.
