This paper shows how to model thin layers and interfaces by asymptotic techniques. Some behaviors are treated: visco-elasticity (Maxwell, Kelvin-Voigt, Norton), Mohr-Coulomb non-associated elasto-plasticity, non-monotone relationship in the strain-stress diagram and contact conditions between the adhesive and the adherents. Numerical validations and algorithms are proposed and presented.

Abstract
This paper shows how to model thin layers and interfaces by asymptotic techniques. Some behaviors are treated: visco-elasticity (Maxwell, Kelvin-Voigt, Norton), Mohr-Coulomb non-associated elasto-plasticity, non-monotone relationship in the strain-stress diagram and contact conditions between the adhesive and the adherents. Numerical validations and algorithms are proposed and presented.File in questo prodotto:
