Hi All,

 I want to model steady waves and to see their effects on a submerged structure and vice versa (i.e. effect of structure on the fluid motion). Becasue of the latter I can't use wave loding in Abaqus/Aqua. I am using Abaqus/CEL with an Eulerian volume.

I will generate waves at one end (the method is still not sure, any suggestions are welcome). The problem is when I define the oposite boundary, where the waves can reflect. I want to model undisturbed waves. I can't make the volume wider as it will make the model bulck for processing.

I am currently conducting biomechanical research on the deflection of the human clavicle during side-impact vehicle collisions. Does anyone have experience with using complex forms of Beam Theory? It may turn out to be fruitless, but I would like to investigate the possibility of using beam theory to model this complex S-shaped bone. Any guidance is much appreciated!

Thank you,

Ali

Dear Guys

I use abaqus cae for modeling and wanna know how should I attech subroutine file to abaqus cae file!

I wanted to get some insight in the transient stress intensity factor (SIF).

In the time history, we notice there is an overshoot (~27%)  from the

steady state SIF for a fixed (not propagating crack). I found the

overshoot occurs at the time when the reflected wave from the opposite

crack-tip comes back to the first crack tip. I wanted to know why this

overshoot occurs, what is the physical explanation?

anyone knows the procedure for solving composite plates in ansys 5.4 or 10.
