Elastic field prediction for a welding repaired material using a semi-analytical method
TL;DR: In this paper, a semi-analytical method (SAM) is developed to tackle problems for material mismatch in a welding repaired material with free surface under remote tensile loading, where the heterogeneous welding bead is modeled by a homogeneous base material containing unknown eigenstrains through the equivalent inclusion method.
Analyse d'un contact thermo-élasto-plastique rugueux par une méthode semi-analytique
TL;DR: In this paper, a semi-analytical formulation for computing the contact between two elastic-plastic solids with rough surfaces is presented, which takes into account the hardening of the material as well as the friction and frictional heating on the interface.
