I am developing an FEA code for a viscoelastic contact analysis. Right now the formulation is assuming small deformations. After deformation I am getting the volume of the body to be less than the original. I want to preserve the volume. ANSYS gives exact results as my code by carrying a normal contact analysis.
Without doing a serious CFD project does anyone know of a back of the envelope calculation or model that will let me show the following. Given:
I am having some trouble getting accurate values for max. stress and max. deflection for an FEM model of a simply supported I-beam in bending. I am using I-DEAS 12 NX to solve the model. I'm pretty new to finite element analysis as a whole, but I know that getting any more
than 10% error (relative to Euler beam theory) in max deflection or stress for a 60x10x8 in. should not happen. Strangely enough, using the same boundary conditions and meshing techniques for a 60x10x8 in. rectangular solid, I find the results I was expecting. Here are some more details:
I am now going to model a sample with metallic glass (Cu-Zr-Ti) under stress and temperature loads. I wonder whether there is some existing database to find material properties, in particular, the creep properties with respect to temperature and stresses. Then I can use these data as input for a FE analysis.
Thank you very much!
Hi all
I am modeling a complex muscle with fibre reinforced. The fibre direction is not constant in this muscle. It is changing with the integration point in the model. Is there anyone who got idea on how to simulate the variable fibre directions in Abaqus? Can user subroutine ORIENT do this?
Many thanks,

I would like to know what is the role of data sampling, data capture rate and bandwidth in case of electromechanical static tensile test. What are their optimum values for a static tensile test of metals according to ASTM standards.
We are deciding to buy Instron 5567 series for 50kN. But we are unable to decide whether that high data acquisition rate, bandwidth is required. Please suggest.
i have an optimization program for structural problem in Matlab software. i found design variables from Matlab. i want to interface this program in to ansys softare to find optimum stress and strain. how can i interface matlab program in to ansys. if any sample tutorilas please send me.
