Topology optimization of 3D truss structures considering stress, displace- ment and buckling constraints

Resumo

This work addresses the development of 3D optimal trusses using the topology optimization method.

The aim is to minimize the total volume with local stress and displacement constraints as well as buckling con-
straints. The augmented Lagrangian method is also implemented to solve the optimization problem. The formu-
lation and the implementation are assesed by means of some benchmark problems found in the literature. Results

also show the importance of properly selecting the material parametrization.
