Reliability-based topology optimization using evolutionary methods for three-dimensional structures analysis

Resumo

This paper addresses structural topological optimization considering the reliability analysis using the
Evolutionary Structural Optimization (ESO) and Smoothing-ESO (SESO) methods, whose heuristics allow that,
at each iteration, whichever elements of the mesh whose contribution to the structure stiffness is considered
inefficient is removed / added during the optimization procedure. A code in Python was developed based on the
minimization of compliance to determine the optimal three-dimensional topologies of an L-shaped structure. The
reliability analysis is performed using First Order Reliability Method (FORM), which aims to obtain a model with
lesser volume and greater stiffness than the deterministic topological optimization (DTO) analysis.
