Topology optimization
Topology optimization
(OP)
As known topology optimization gives a good stiffness to weight ratio. However I cannot make my mind if the structure that is stiffness-wise efficient, stregth-wise efficient too. If we fix the stress concentrating sharp radiuses, do we get a nice structure strength-wise?





RE: Topology optimization
- In general no. Increasing a fillet radius to eliminate a stress concentration is very unlikely to make any significant difference to the overall stiffness of the structure. However if you "fix" the problem by changing the section base dimensions then the answer is possibly yes.

RE: Topology optimization
or is it not possible to generalize? correct
run your optimization with applied loads and strength criteria, and be sure to check both material strength modes as well as structural strength modes (buckling, etc)
