Structural Topology Optimization

[rjyang]

Dear Colleagues,

I am looking for any ideas, e.g., Structural Topology Optimization for determining load path for crash simulations. I appreciate any suggestions. Thanks.

Hello Ren-Jye,

Have you looked at LS-Dyna/LS-Opt to do that?

Hi Ren-Jye,

One of my doctoral students and I are working on a related topic.
We have not done any topology optimization for alternate load paths yet. We are still in the stage of investigating how to identify these alternate load paths and correlate the nature of these alternate load paths to damage tolerance and failure predictability.
We found there is some work from the civil engineering community designing frame structures. Under collapse conditions they look at "alternate load paths" that redirect loads and provide damage tolerance.

It is a much less explore area that I had imagined it to be.

Hi,Do you have used LCDs, second hand LCDs and used flat screens and used LCD monitors? Please go here:www.sstar-hk.com(Southern Stars).We are constantly buying re-usable LCD panels and working for LCD recycling.The re-usable panels go through strictly designed process of categorizing, checking, testing, repairing and refurbishing before they are re-used to make remanufactured LCD displays and TV sets.Due to our recent breakthrough in testing and repairing technology of LCD, we can improve the value for your LCD panels.
