On the role of enrichment and statical admissibility of recovered fields in a-posteriori error estimation for enriched finite element methods
Octavio A. González-Estrada, Juan José Ródenas, Stéphane P. A. Bordas +3
Purpose: This paper aims at assessing the effect of (1) the statical admissibility of the recovered solution; (2) the ability of the recovered solution to represent the singular so…
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…
Local/global model order reduction strategy for the simulation of quasi-brittle fracture
Pierre Kerfriden, Jean-Charles Passieux, Stephane Pierre-Alain Bordas
This paper proposes a novel technique to reduce the computational burden associated with the simulation of localised failure. The proposed methodology affords the simulation of dam…
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…
Linear free flexural vibration of cracked functionally graded plates in thermal environment
S Natarajan, PM Baiz, M Ganapathi +2
In this paper, the linear free flexural vibrations of functionally graded material plates with a through center crack is studied using an 8-noded shear flexible element. The materi…
Natural frequencies of cracked functionally graded material plates by the extended finite element method
S Natarajan, PM Baiz, S Bordas +2
In this paper, the linear free flexural vibration of cracked functionally graded material plates is studied using the extended finite element method. A 4-noded quadrilateral plate…
