Scope

The aim of this international workshop is to honor Jean-Baptiste Leblond on the occasion of his 60th birthday, for his important contribution to several branches of solid mechanics.

Jean-Baptiste's main activities have concerned:
- The mechanics of brittle fracture. Jean-Baptiste contributed significantly to the determination of closed form solutions of the crack tip stress intensity factors for various complex geometries (interface crack, kinking, in-plane and out-of-plane crack deformations ...) using asymptotic and perturbation approaches. Applications concern mainly the modelling of crack propagation paths whether for two dimensional, or for three dimensional situations, with major contributions about the influence of heterogeneities and mode I+III loading conditions.
- The ductile fracture of metals. Jean-Baptiste contributed to the development of homogenized models of ductile failure using limit-analysis theory. The major developments concern the study of viscoplastic porous solids, the derivation of void growth models for spheroidal voids (GLD model) and general ellipsoidal voids (ML Model) for the prediction of shear-dominated failure, and the development of analytical coalescence criteria by internal necking.
- The numerical simulation of thermomechanical processing of metallic alloys, together with the theoretical study of associated problems of material behaviour. Jean-Baptiste contributed notably to the development of transformation plasticity models and the simulation of welding processes including fluid flow.
- The study of reaction–diffusion in solids. Important developments concern the modelling and simulation of internal oxidation problems.
- The development of advanced numerical methods in solid mechanics and metallurgy.

The workshop will thus cover various topics in solid mechanics, with a particular emphasis on theoretical modeling and numerical treatments of brittle and ductile fracture problems. It will also include other contributions pertaining to topics in which Jean-Baptiste has shown a great interest. His colleagues, students and friends will present theoretical, computational and experimental results in subjects dear to him.
