Hello everyone.
I'm trying to apply the Tsai-Wu criteria to a composite plate in ANSYS. I'm using the SHELL99 element.
However, when I input the data for the criteria an error occours and ANSYS won't show me any results on the criteria.
Can someone help me? How do I use this criteria and what data should I use?
Thanks in advance

What is the difference between CP,CERig and RBE3 used in ANSYS, Can anyone please explain clearly
i'm studying M.S(materials science) and i"m interested in knowing how to do a project work in indenting and extracting mechanical properties of materials using ABAQUS software or using MATLAB. suggest any idea thanks a lot in advance. have a nice time.
In fatigue analysis, it is common to use S-N curve from database for spesific material, and some time for spesific way of loading. Is there any way to predict fatigue from direct simulation? For example, giving cyclic loading (10^5 times) and the material will suffer damage and eventually failed. In some FEM codes (MARC, LSDYNA, etc) there is Lemaitre-Chaboche model used to analyze material behavior under low cycle cyclic loading.
Thanks in advance

Hi all,
I ran a pre-buckling analysis using ABAQUS. I chose nanometer as my length unit. So for the Young's modulus, since my sample has 100 GPa for the Young's modulus, I put 0.0000001 as the value for the Young's modulus under the material property in the ABAQUS.
However, the resulted eigenvalue (~2 nN) was not as what I expected (~2uN). Based on the calculation based on the Euler buckling theory, the critical load should be around 2 uN.
