The analysis of complex systems may be more effectively handled considering the combination of different numerical methods, in a way that each numerical technique can be applied to deal with the particularities of the model that better fit its positi... see more

Topology Optimization (TO) is recognized as an important approach during early stages of structural concept. It allows the designer for finding higher performance solutions taking into account the limitation of natural resources. Most computational T... see more

In this work we will present the computation of moments in the anisotropic plane elasticity fast multipole formulation. Fundamental solutions of plane elasticity are represented by complex functions from the classical 2D elasticity theory. The Multip... see more
