Bi-directional evolutionary structural optimization for design-dependent fluid pressure loading problems

摘要: This article presents an evolutionary topology optimization method for compliance minimization of structures under design-dependent pressure loads. In traditional density based methods, intermediate values densities the solid elements arise along iterations. Extra boundary parametrization schemes are demanded when these methods applied to loading problems. An alternative methodology is suggested in this handling type load. With extended bi-directional structural associated with a partially coupled fluid–structure formulation, loads modelled hydrostatic fluid finite elements. Due discrete nature method, problem solved without any need load surfaces parametrization. Furthermore, introduction separate domain allows algorithm model non-constant fields Laplace's equation. Three benchmark examples explored order sho...
