johnhors, maybe I am not clear with my question. The structure obtained from topology optimization is already very good at stiffness. I am asking that: is a stiffness-wise efficient structure also good strength-wise? or is it overweight? or is it not possible to generalize...
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?
Impact tests are never on such a scale that can be considered too frequent to hamper developement. So do you also not like tensile tests? or chemical analysis of kinds? Charpy test is so easy and need such a basic equipment that it is not even worth thinking. How do you know that materials that...
There is GPUTop that does topology optimization based on GPU, but their link is off. Their website was saying that performance was 60x better that CPU. And the source code is awailable, but no compiled form. If I find the link again I will post it in my blog...
