Deformation gradients and atomistic simulations
I came upon a recent paper called "Deformation gradients for continuum mechanical analysis of atomistic simulations" by Jonathan A. Zimmerman , Douglas J. Bammann, and Huajian Gao, International Journal of Solids and Structures 46 (2009) 238–253 where the authors conclude with

User Element for Ansys
Hi,
I ask for help. I need to implement a user element for shell element in Ansys, and I ask if somebody know how to do this or can send me some example. I try to read something but I not found a good example about user element in Ansys Thanks a lot.
an epitaxial question
Hi, everybody, i had one problem. see the attached image.
Does anyone know how to get the strain function or strain energy of the perfect epitaxial film? Or could you recommend some textbooks or references about this topic?
Thank you
Simple beam simulation in Abaqus
Hi everyone,
I have modelled a simple beam using continuum elements to assess the mechanical behaviour. The results are quite good since it could predict deflection close to test data. Using ABAQUS general-purpose shell elements, the deflection is quite small compared to test results ie it appears the material has become more stiff. Can any one give me a clue?
Many thanks in advance,
Emmanuel
Complicated rotor dynamic simulation with ANSYS/ABAQUS or Madyn 2000
I have a system as in the Figure. There will have a radial load and a lateral load acting on the circumference of the drum which rotate at around 1000 rpm. I want to investigate the stability of the shaft at this speed. Can ANSYS or ABAQUS simulate this kind of dynamic simulation or is there any other software can solve my problem.
Thank you.
