Balancing Domain Decomposition with Nonlinear Relocalization: Parallel Implementation for Laminates

摘要

Over the past thirty years, composite materials have been used increasingly in industry, especially in the aeronautical and spatial industries. Therefore, there is a great interest in the prediction of their degradation. The objective of this work is to develop a program capable of simulating structures on an industrial level using the latest models developed. In the first section, we present a review of the damage mesomodel used for the simulations. The second section presents the partition technique, and the parallel resolution technique utilized for the simulation. A new Newton loop is added to the classic algorithm to improve the performance in the case of localized nonlinearities. The third section present the implementation on a C++ home made finite element code. And the technique utilized to parallelized the problem. Finally, the forth section gives illustrations showing the level of performance which can be expected from such an approach.
