How to cut finite elment model from a geometry model?
Forums
Hello all! I imported an .inp file model which was converted from another .am file into Abaqus. This model (model 1) doesn’t include any geometry information but only has 3D finite element model. I want to create an air model (Cube) surrounding model 1, subtracting model 1 from air model and leave a hole whose shape is the same as model 1. Then I want to insert model 1 to the hole again and compute acoustic problem. The question is: I can’t use ‘cut/merge’ function in Abaqus because there is no geometry information in model 1. Could someone tell me how to do that? Thanks very much.
Continuum interpretation of virial stress in molecular simulations
Arun K. Subramaniyan and C. T. Sun, accepted for publication in International Journal of Solids and Structures, doi:10.1016/j.ijsolstr.2008.03.016
The equivalence of the virial stress and Cauchy stress is reviewed
using both theoretical arguments and numerical simulations. Using
thermoelasticity problems as examples, we numerically demonstrate that
virial stress is equivalent to the continuum Cauchy stress. Neglecting
How to do sound transmission in solid in Abaqus?

Hello all. I am a phd student from UNB. Now I want to use Abaqus to simulate acoustic problem which is sound transmission from fluid such as air to solid. The outputs I want to get are acoustic pressure in fluid and solid, especially inside solid. What I did before is treating solid as fluid by using acoustic medium. However, the mechanics of solids are fundamentally different from fluids, and its not sensible to treat them the same. For example solids support shear, while fluids do not. Hope someone could answer my question. Thanks a lot.

a question about ALE method

hi, I'm a student studying ALE method. In the book of "Nonlinear Finite Elements for Continua and Structures" written by Ted Belytschko el, conservation equations which discribed in the reference configuration and current configuration are given out (see chapter 7). But how about Balance Laws in initial configuration?
a review of a paper by HD Bui found in the internet !!
dear iMechanica friends
I came across a review of a paper by HD Bui who was somewhere in the internet, and I find it is very interesting. I could even have written this review myself !! I don't think the reviewer exaggerates....

difficulties CONTACT problem with plasticity using ABAQUS FEA code.
Hello everyone:
1. I have built a FEM model 2D plane strain using ABAQUS/Standard (CPE4R) elements,
2. I am modeling the contact between a cylinder and a plate in 2D.
3. The Cylinder material is given is ELASTIC ISOTROPIC material with no plasticit E=310 GPa
4. The plate is with a Ramberg-Osgood plasticity with a Young's modulus E=210 GPa.
5. The mesh at the the contact point is VERY refined element characteristic length is about 1 micron. (My model units are (mm,N,sec)).
