Optimization of a honeycomb structure
Optimization of a honeycomb structure
(OP)
Hello guys
I created a honeycomb structure under blast loads using the Dynamic/Explicit step. But due to Abaqus inability to optimize explicit analysis I had to mirror the blast loads into static loads under Static, General step. The results aren't perfect but it will do. Now if anyone could tell me how to proceed with the optimization I would be grateful.
I want to reduce peak displacement but optimizing the honeycomb core only, the idea behind this is for Abaqus to determine the optimal geometry of the core to resist blast loads.

How you optimize will greatly depend on your design variables that you have. Can you change the honeycomb geometry or is it a pre-manufactured part. With more details and some images we will be able to help more.
I hope this helps.

RE: Optimization of a honeycomb structure
This is the picture of the honeycomb core. My objective is be to optimize the cell angle to find the optimal angle that can resist blast loads.
This is the picture of the honeycomb structure where I had to create 14 partitions and applied 14 pressure loads (with amplitude)on each partition to mirror the blast load.
Now is it possible for abaqus to optimize for optimal geometry with the given information. Thanks a lot I appreciate the help.

As far as I can see, you want to do a parametric optimization of the design variables of the structure. I think Isight, A/CAE (+Python) and A/Explicit should do the job.
