Topology optimization of three-dimensional structures subject to self-weight loading

What is it about?

Topology optimization of structures under self-weight loading is a challenging problem which has received increasing attention in the last years. The use of standard formulations based on compliance minimization under volume constraint suffers from numerous difficulties for self-weight dominant scenarios, such as non-monotonic behaviour of the compliance, possible unconstrained character of the optimum and parasitic effects for low densities in density-based approaches. In the paper we propose an alternative approach for dealing with topology design optimization of structures into three spatial dimensions subject to self-weight loading.
