A partitioned model order reduction approach to rationalise computational expenses in multiscale fracture mechanics
Pierre Kerfriden, Olivier Goury, Timon Rabczuk +1
We propose in this paper an adaptive reduced order modelling technique based on domain partitioning for parametric problems of fracture. We show that coupling domain decomposition…
Statistical extraction of process zones and representative subspaces in fracture of random composite
Pierre Kerfriden, Karl Michael Schmidt, Timon Rabczuk +1
We propose to identify process zones in heterogeneous materials by tailored statistical tools. The process zone is redefined as the part of the structure where the random process c…
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…
