Parallel Multiscale Numerical Framework of the Non-linear Failure Analysis for Three-Dimension Composite Structures

Parallel Multiscale Numerical Framework of the Non-linear Failure Analysis for Three-Dimension... A parallel multiscale numerical framework based on the FE2 method is established to perform the non-linear failure analysis of three-dimension (3D) composite materials with complicated architectures. Parallelization of the nested solution process is presented, as well as the strategy used to implement the FE2 method alongside the finite element package ABAQUS. The emphasis is put on the detailed numerical implementation in both scales, using a set of python scripts and UMAT subroutines to allow the service of commercial finite element packages ABAQUS instead of the in-house code. The novel framework can be scalable to the distributed clusters and carries out the progressive damage analysis of 3D braided composite materials under uniaxial tensile loading and three-point bending loading, respectively. As a validation, the results obtained have been compared with experimental data from the literature. The parallel performances of numerical examples in runtime and acceleration effect are addressed to demonstrate the capabilities of the proposed framework. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Aeronautical and Space Sciences Springer Journals

Abstract

A parallel multiscale numerical framework based on the FE2 method is established to perform the non-linear failure analysis of three-dimension (3D) composite materials with complicated architectures. Parallelization of the nested solution process is presented, as well as the strategy used to implement the FE2 method alongside the finite element package ABAQUS. The emphasis is put on the detailed numerical implementation in both scales, using a set of python scripts and UMAT subroutines to allow the service of commercial finite element packages ABAQUS instead of the in-house code. The novel framework can be scalable to the distributed clusters and carries out the progressive damage analysis of 3D braided composite materials under uniaxial tensile loading and three-point bending loading, respectively. As a validation, the results obtained have been compared with experimental data from the literature. The parallel performances of numerical examples in runtime and acceleration effect are addressed to demonstrate the capabilities of the proposed framework.
