Hi
I am trying to optimize a part for which I have to reduce its weight and maintain its strength at the same time.
What responses and constraints am I supposed to give ? And based on what grounds should I decide this ?
`Hi,
What type of optimization you are looking at?
There are few commonly used/suggested topology formulations are furnished on OptiStruct help. You can refer to those to start with.

Hi Prakash,
I am trying to do a topology optimization for my part and the main goal is to reduce its weight at the same time support the loads. Correct me if I am wrong.
For increasing/maintaining the strength, I am giving min weighted compliance as an objective function and the yield stress of the material as a stress constraint.
OR
For reducing its weight, if I give min Volume fraction as objective function and the yield stress as stress constraint.
Which one is correct ?
Also, i couldn't find the above screenshot in the optistruct help. Can you direct me to it ?
Thank you
Vignesh
Hi Vignesh,
I personally prefer using volume fraction as a response instead of stress because minimizing compliance means increasing the stiffness and constraint on stress doesn't really fit your requirement.
Thank you for the response. I will work on it and get back to you if I face any trouble.
