Document scanné à partir de sa version papier originale de 1997The aim of the thesis is to design tool for engineers simple to use which is able to analyze 3D stresses responsible for edge delamination or transverse crackings in multilayed materials. In the first part of the dissertation, we built Multiparticle Models (M4) from 3D approximate stresses written as Legendre's z polynomials layerwise. Polynomial coefficients are (x, y) fields which are connected to generalized stresses. We use Hellinger-Reissner's formulation to deduce displacements and associate generalized strains. Writing the formulation stationary, we give equilibrium equations, boundary conditions and constitutive laws. According to the different approximate stress fields,...
