I've done some simulation of stress wave propagation in Hopkinson pressure bars (which are effectively wave guides) in ABAQUS, for homogeneous materials. I good very good correlation with the theoretical solution, and reasonable correlation with experiments. In the experiment I was modelling there were other complications that may have dominated the error rather than the accuracy of the wave modelling. Bear in mind that the higher the frequency you go there will always be a divergence between the "real" solution and the prediction of an explicit numerical scheme - K.J. Bathe's book (Finite Element Procedures in Engineering Analysis) has a good description of this.

I haven't worked with ANSYS, but seeing as it uses the DYNA code, it may have better material models for composites than ABAQUS.  

hi, Govender,

Thanks a lot!!

 I chose ABAQUS finally. For explicit analysis, I use the commond to make the .sel file after the analysis, I want to convert it to .fil file. However, it seems a problem.

I use the commond "abaqus job=<file name> convert=all", but there is no any file produce after that, does anyone know the reason?

Thank you very much

Hi, all

I am studying
Mech. Engineering and I have just started using ANSYS. I am trying to simulate
the lamb wave propagation in a plate. My idea is to create a 2D model and use
transient response. But ANSYS gives me the movement of the bar, mode shapes...but
nothing like wave. Can you help me in this? How can I simulate the problem...

Thank you
in advance...Just remember that I don't have a lot of experience in ANSYS...

Hi all,

I'm trying  to simulate  with ABAQUS a explosion of TNT and the effect of that on a metal panel. The metal panel is 200mm away from explosive. It is about 100g TNT. I now about the subroutine VDLOAD. Which options I could use else in ABAQUS? Is it posible to define a explosion lake this with *EOS? If yes, which element type I should use for explosive set? Should I define a element set for air, if I use *EOS?

 Thank you
