I mesh most of my parts in C3D8R. My simulation are quasi-static, and involve a lot of contacts. To model steel, I use a classic elastic-plastic behavior, coming from stress-strain curves we measured. I have the yield strength of the material and the strain at break. My questions concern post-processing.
dear all,
Finally i found out the way to simulate PMMA embossing using Mooney Revlin constants at several tempature. Now i am trying to include Prony model and shift function with Hyperelastic model in ansys. I tried using static and transient analysis but it is not giving viscoelastic flow behaviour. If anyone done this kind of simulation in Ansys please help me. I am sending mooney revlin and prony model constants in ansys WB.
To be included in command file..

Dear Colleagues,
I am studying on Interlaminar Properties of 3D Textile Composites. Especially I am focusing on Fracture Toughness of Stitched Composites. Anyone can suggest useful Journal Papers about Stitched Composites and/or Mode I- Mode II Testing for Literature review?
Kind Regards,

The three by three matrix is a workhorse for mechanicians, yet the study of this tool is seldom addressed mathematically. One reason is that the space of such matrices is nine-dimensional, quite beyond diagrams and vision. The advantage of a mathematical investigation of the matrix space is clear in the study of two by two real matricies where rotations, shears, and squeezes correspond to area-preserving transformations of the plane. For transformations of space that preserve volume there is a much richer variety of phenomena that may correspond to mechanical events.
Hi, everyone:
I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.
When I simulated the beam with shell element, first I define reference points at both end of the beam and assign 'RIGID BODY/PIN OR TIE' to nodes at the edge,after that I applied bending moments and boundary conditions to both reference points. But after I finished the buckling analysis, the result is not reasonable,the eigen value is about two times the the value I expected.
