Continuous Wave simulation in Abaqus

Submitted by Ranil Banneyake on

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.

Reminder - abstract submission for 1st IC Abrasive Processes

Submitted by Dean Eastbury on

Evolving from earlier meetings on erosion, the International Conference on Liquid and Solid Impact (ELSI-IX) and the International Conference on Erosive and Abrasive Wear (ICEAW-II), the 1st International Conference on Abrasive Processes (ICAP-I) will be held in the historic city of Cambridge, England, 21-25 September 2008.

You are invited to join international delegates for this fully residential conference by submitting an abstract by 27 January 2008. Details can be found at www.icap.elsevier.com

Has anyone tried using beam theory on an S-shaped beam?

Submitted by BSMEwahoo on

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

Why does the overshoot occur in Dynamic Stress Intensity Factor

Submitted by Sandip Haldar on

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?
