Improved recovery of admissible stress in domain decomposition methods - application to heterogeneous structures and new error bounds for FETI-DP
Augustin Parret-Fréaud, Valentine Rey, Pierre Gosselet +1
This paper investigates the question of the building of admissible stress field in a substructured context. More precisely we analyze the special role played by multiple points. Th…
On the computation of plate assemblies using realistic 3D joint model: a non-intrusive approach
Guillaume Guguin, Olivier Allix, Pierre Gosselet +1
Most large engineering structures are described as assemblies of plates and shells and they are computed as such using adhoc Finite Element packages. In fact their computation in 3…
Strict lower bounds with separation of sources of error in non-overlapping domain decomposition methods
Valentine Rey, Pierre Gosselet, Christian Rey
This article deals with the computation of guaranteed lower bounds of the error in the framework of finite element (FE) and domain decomposition (DD) methods. In addition to a full…
Substructured formulations of nonlinear structure problems - influence of the interface condition
Camille Negrello, Pierre Gosselet, Christian Rey +1
We investigate the use of non-overlapping domain decomposition (DD) methods for nonlinear structure problems. The classic techniques would combine a global Newton solver with a lin…
A quasi-optimal coarse problem and an augmented Krylov solver for the Variational Theory of Complex Rays
L Kovalevsky, Pierre Gosselet
The Variational Theory of Complex Rays (VTCR) is an indirect Trefftz method designed to study systems governed by Helmholtz-like equations. It uses wave functions to represent the…
