Implanté sur deux sites, le campus d’Angers et le pôle de réalité virtuelle de Laval, le LAMPA intervient dans les domaines de l’innovation, des procédés avancés de fabrication et de durabilité des matériaux et des structures. Le numérique et le virtuel sont au cœur des travaux de recherche, par exemple la simulation numérique du procédé pour la compréhension des phénomènes thermiques et mécaniques en jeu.

  Correlation between microstructure and cyclic behavior of 316L stainless steel obtained by Laser Powder Bed Fusion 

  Article dans une revue avec comité de lecture

  LIANG, Xiaoyu; HOR, Anis; ROBERT, Camille; SALEM, Mehdi; MOREL, Franck (Wiley, 2022-02-23)

  In this work, stainless steel 316L obtained by Laser Powder Bed Fusion (L-PBF) has been produced and characterized. The experimental campaign focuses on the samples in the as-built state under cyclic tension-compression ...

  Numerical investigation of the surface and microstructure effects on the high cycle fatigue performance of additive manufactured stainless steel 316L 

  Article dans une revue avec comité de lecture

  LIANG, Xiaoyu; ROBERT, Camille; HOR, Anis; MOREL, Franck (Elsevier BV, 2021-04-09)

  This paper aims to study the individual and competitive effects of surface defects and microstructural compo­nents in an AM 316L by numerical methods. Based on the microstructure sensitive modeling framework, nu­merical ...

  Surrogate parametric metamodel based on Optimal Transport 

  Article dans une revue avec comité de lecture

  TORREGROSA, Sergio; CHAMPANEY, Victor; AMMAR, Amine; HERBERT, Vincent; CHINESTA, Francisco (Elsevier B.V., 2021-11-30)

  The description of a physical problem through a model necessarily involves the introduction of parameters. Hence, one wishes to have a solution of the problem that is a function of all these parameters: a parametric ...

  Domain decomposition involving subdomain separable space representations for solving parametric problems in complex geometries 

  Article dans une revue avec comité de lecture

  KAZEMZADEH-PARSI, Mohammad Javad; AMMAR, Amine; CHINESTA, Francisco (Springer, 2022)

  A domain decomposition technique combined with an enhanced geometry mapping based on the use of NURBS is considered for solving parametrized models in complex geometries (non simply connected) within the so-called proper ...

  Data-Driven Modelling of Polyethylene Recycling under High-Temperature Extrusion 

  Article dans une revue avec comité de lecture

  CASTÉRAN, Fanny; DELAGE, Karim; HASCOËT, Nicolas; AMMAR, Amine; CHINESTA, Francisco; CASSAGNAU, Philippe (MDPI AG, 2022-02-18)

  Two main problems are studied in this article. The first one is the use of the extrusion process for controlled thermo-mechanical degradation of polyethylene for recycling applications. The second is the data-based modelling ...

  Observations on the influence of process and corrosion related defects on the fatigue strength of 316L stainless steel manufactured by Laser Powder Bed Fusion (L-PBF) 

  Article dans une revue avec comité de lecture

  MEROT, Pierre; MOREL, Franck; GALLEGOS MAYORGA, Linamaria; PESSARD, Etienne; BUTTIN, Paul; BAFFIE, Thierry (Elsevier BV, 2021-10-06)

  Corrosive environments are known to be detrimental to the mechanical strength of metallic alloys. In the case of 316L stainless steel, the main corrosion mechanism observed is pitting, which leads to localized rough defects. ...

  Effects of continuous and discontinuous non-relevant stimulus on creativity 

  Article dans une revue avec comité de lecture

  MILLE, Charles; CHRISTMANN, Olivier; FLEURY, Sylvain; RICHIR, Simon (Informa UK Limited, 2022-06-02)

  Innovation is made of different tasks from strategic positioning to the first phases of production. One of the main activities is the generation of ideas through different creativity phases. These creativity activities are ...
