Resumen:
A numerical evolutionary procedure for structural optimisation of two-dimensional structures is presented in this paper. The methodology is originally based on the Biological Growth Method (BGM) 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.
