A new parallel sparse direct solver: Presentation and numerical experiments in large-scale structural mechanics parallel computing

Autor: F. X. Roux, Georges Cailletaud, S. El Arem, F. Feyel, I. Guèye

Publikováno v: International Journal for Numerical Methods in Engineering. 88:370-384

The main purpose of this work is to present a new parallel direct solver: Dissection solver. It is based on LU factorization of the sparse matrix of the linear system and allows to detect automatically and handle properly the zero-energy modes, which

Modelling of the compression behaviour of metallic hollow-sphere structures: About the influence of their architecture and their constitutive material’s equations

Autor: V. Marcadon, F. Feyel

Publikováno v: Computational Materials Science. 47:599-610

This paper is dedicated to the study of the mechanical behaviour of metallic hollow-sphere structures under quasi-static compressive loads and, especially, to the characterization of contributions of both the stacking architecture and the constitutiv

Size effects in metal matrix composites

Autor: Jean-Louis Chaboche, L.P. Kubin, Benoit Devincre, F. Feyel, Arjen Roos, Sébastien Groh

Publikováno v: Materials Science and Engineering: A. :279-282

The mechanical properties of Al / Al 2 O 3 metal matrix composites are investigated using a 3D discrete-continuum simulation of dislocations and plasticity. The variations of the yield stress as a function of fibre volume fraction can be predicted fr

Acta Materialia, Elsevier, 2003, 51 (4), pp.1133-1141. ⟨10.1016/S1359-6454(02)00518-9⟩

An elastoviscoplastic finite element model is proposed to assess the bond-coat/oxide interface critical energy release rate in an EBPVD thermal barrier coating (TBC). The local stress fields responsible for the crack initiations are analyzed at the i

Modelling crystal plasticity by 3D dislocation dynamics and the finite element method: The Discrete-Continuous Model revisited

Autor: Sébastien Groh, Benoit Devincre, Arjen Roos, R. Gatti, A. Vattré, F. Feyel, O. Jamond

Publikováno v: Journal of the Mechanics and Physics of Solids
Journal of the Mechanics and Physics of Solids, Elsevier, 2014, 63, pp.491-505. ⟨10.1016/j.jmps.2013.07.003⟩

A unified model coupling 3D dislocation dynamics (DD) simulations with the finite element (FE) method is revisited. The so-called Discrete-Continuous Model (DCM) aims to predict plastic flow at the (sub-)micron length scale of materials with complex

Multiscale non linear FE2 analysis of composite structures : Fiber size effects

Autor: F. Feyel

Publikováno v: Le Journal de Physique IV. 11:Pr5-195

An imbricated finite element technique has been recently developed in the context of multiscale inelastic analysis of composite structures. The constitutive equations in the classical overall inelastic analysis are replaced by a lower level finite el

A first step to Fluid-Structure interaction inside Solid Propellant Rocket Motors

Autor: S. Cerqueira, F. Feyel, G. Avalon

Publikováno v: WIT Transactions on The Built Environment.

Self sustained oscillations in Solid Propellant Rocket Motors result from an aeroacoustic phenomenon involving interaction between vortex shedding and acoustics of the chamber. An experimental investigation has been carried out with a cold gas appara
