The Coupling Of The Biological Growth Method And The Boundary Element Method For Structural Shape Optimisation
Abstract
A numerical evolutionary procedure for structural optimisation of two-dimensional structures
based on the Biological Growth Method (BGM) is shown and is implemented using two Boundary
Element Method (BEM) formulations: the standard for two-dimensional elastostatics for the stress or
strain analysis, and the Dual Reciprocity Method (DRM) for modelling the swelling/shrinking of the
optimisation domain. Advancing previous work done by the authors on the original stress formulation of
the BGM, tangential strains are used as objective functions in this paper.
