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.

Contribution à la prise en compte des effets du procédé de mise en forme sur la tenue en fatigue des matériaux métalliques

PESSARD, Etienne (2020)

Les travaux de recherche présentés dans ce mémoire se concentrent sur la prise en compte de l’effet du procédé sur la tenue en fatigue à grand nombre de cycles des matériaux métalliques (entre 10⁵ et 10⁷ cycles). Ces travaux ...

A Comparative Study on Conventional versus Immersive Service Prototyping (VR, AR, MR)

RAZEK, Abdul Rahman Abdel; VAN HUSEN, Christian; PALLOT, Marc; RICHIR, Simon (ACM Press, 2018)

Product prototyping, through the use of immersive technologies, has demonstrated its huge potential enabling co-creative exploration of different usage scenarios and evaluation of the User eXperience. It is already an ...
Domain name valuation: Typology and verification of research hypotheses

GENTY, Clément (2017)

Domain names are digital tools that make it easy to locate on the Internet. Only, speculation and gain applause have prompted the registries managing the first-level extensions to liberalize hierarchical levels. So, while ...
A Proposed Research Framework and Model for Service Prototyping

RAZEK, Abdul Rahman Abdel; VAN HUSEN, Christian; PALLOT, Marc; RICHIR, Simon (IEEE, 2018)

Companies around the world are willing to improve their new service development process through the use of service prototyping. We report in this paper about the first part of our research study on service prototyping that ...
Development of a Hyperelastic Constitutive Model Based on the Crystal Plasticity Theory for the Simulation of Machining Operations

BEN BOUBAKER, Houssem; MAREAU, Charles; AYED, Yessine; GERMAIN, Guénaël; GUERIN, Fabrice (Elsevier BV, 2019)

In this work, a hyperelastic constitutive model is developed to describe the thermo-mechanical behavior of the Ti17 titanium alloy. The grain shape and the crystallographic orientation are explicitly taken into account. ...
Surface Integrity When Machining Inconel 718 Using Conventional Lubrication and Carbon Dioxide Coolant

CHAABANI, Sana; ARRAZOLA, Pedro José; AYED, Yessine; MADARIAGA, Aitor; TIDU, Albert; GERMAIN, Guénaël (Elsevier BV, 2020)

Surface integrity induced by machining process affects strongly the performance of functional products, for instance, the fatigue life as well as the resistance to stress corrosion cracking. Consequently, it is relevant ...
