Journal ArticleDOI
Characterization of the mechanical properties of skin by inverse analysis combined with the indentation test
TL;DR: This study proposes a new method to determine the mechanical properties of human skin by the use of the indentation test and consists of combining experimental results with a numerical finite elements model in order to find out the required parameters.
Journal ArticleDOI
A nonlinear elastic behavior to identify the mechanical parameters of human skin in vivo.
TL;DR: An inverse method that can be adapted to any kind of mechanical tests and behavior laws is presented and used to identify the mechanical properties of the human skin tissue in vivo.
Journal ArticleDOI
Identification of a friction model—Application to the context of dry cutting of an AISI 316L austenitic stainless steel with a TiN coated carbide tool

TL;DR: In this paper, a new tribometer has been designed in order to reach relevant values of pressures, temperatures and sliding velocities at the tool-chip-workpiece interface for dry cutting of an AISI316L austenitic stainless steel with TiN coated carbide tools.
Journal ArticleDOI
3D modelling of multipass welding of a 316L stainless steel pipe
TL;DR: In this paper, a 3D finite element simulation of multipass welding of a 316L stainless steel pipe is presented, which includes 13 weld passes and the simulation has been achieved using adaptive mesh refinements and a procedure to transport the results between the different meshes.
Journal ArticleDOI
Numerical modelling of orthogonal cutting: influence of numerical parameters
TL;DR: In this article, the influence of mesh density and hourglass on chip local removal was studied and the choice of consistent parameters to validate numerical models is of primary importance to be able to compare experimental and numerical results.
