Improved multiscale computational strategies for delamination
Olivier Allix, Pierre Gosselet, Pierre Kerfriden
This paper presents a three-scale computational strategy for the study of composite modeled at the mesoscale so that delamination can be reliably simulated. The solver is based on…
A three-scale domain decomposition method for the 3D analysis of debonding in laminates
Pierre Kerfriden, Olivier Allix, Pierre Gosselet
The prediction of the quasi-static response of industrial laminate structures requires to use fine descriptions of the material, especially when debonding is involved. Even when mo…
On the control of the load increments for a proper description of multiple delamination in a domain decomposition framework
Olivier Allix, Pierre Kerfriden, Pierre Gosselet
In quasi-static nonlinear time-dependent analysis, the choice of the time discretization is a complex issue. The most basic strategy consists in determining a value of the load inc…
A relocalization technique for the multiscale computation of delamination in composite structures
Olivier Allix, Pierre Kerfriden, Pierre Gosselet
In this article, we present numerical enhancements of a multiscale domain decomposition strategy based on a LaTIn solver and dedicated to the computation of the debounding in lamin…
Bridging Proper Orthogonal Decomposition methods and augmented Newton-Krylov algorithms: an adaptive model order reduction for highly nonlinear mechanical problems
Pierre Kerfriden, Pierre Gosselet, Sondipon Adhikari +1
This article describes a bridge between POD-based model order reduction techniques and the classical Newton/Krylov solvers. This bridge is used to derive an efficient algorithm to…
