Topology optimization using stress
Altair EmployeeHi,
I want to make a 1D topology optimization of two plates bolted together (PBEAM elements). There is 12 holes where bolt can be positioned. I want to find the best place where to put the bolts with a minimum number of 6 bolts. The objective is to minimize the Von Mises stress in one of the plate. I have difficulties to choose the right parameters, responses, constraints and objectives.
It is like tutorial 'OS-2040: Spot Weld Reduction using CWELD and 1D Topology Optimization ', but incorporing stress responses.
Can you give me some hints / advices ?
Thank you
Benjamin

Stress constraints do not apply to 1D elements.Please have look on below post similar to your requirement,

Thanks again !
In my model, I want to apply my stress constraint on 2D elements (PShell elements) of the 2 plates. Is that possible if my design variable is on 1D element (Pbeam elements) ?
Another scenario would be to minimize the Stress of the 2D elements and having a constraint on the volume fraction response? Is that possible ?
