I am not able to decide what design responses I need to take? Should I take displacement or stresses? I am having problem in deciding upper and lower bound of those responses.
@alekh
To start with you can use compliance and volume fraction and you can then fine tune your design.
I have tried with volume fraction -0.4 stress upper bound corresponding to fos 3 with objective as minimize mass but the shape after optimization is not proper.I have even tried with draw direction but still its not proper. i want to look for the shape which can be fabricated.
Can you share the file?
what do you mean the shape is not proper and kindly let us know your expectations.
