Evaluation of Effective Properties of Heterogeneous Media Through a General Purpose Graphics Processing Unit (GPGPU) Based Algorithm

Abstract

The aim of this paper is to present the application of a parallel Finite Elements Method (FEM) code based on General Purpose Graphics Process Units (GPGPU) to the evaluation of effective mechanical properties of periodic media. The multiscale technique adopted herein is the Asymptotic Expansion Homogenization (AEH), which demands considerable computational effort even for simple geometrical and mechanical material models. In this work, the AEH technique is implemented on a GPGPU basis. The preliminary results indicate a considerable speedup in comparison with a sequencial version of the employed code.
