Mécanique de l’endommagement non-local avec interactions évolutives pour la modélisation des matériaux quasi-fragiles : endommagement anisotrope et approche Eikonale à gradient implicite

La prédiction de la fissuration est essentielle pour évaluer la durabilité d’une structure sous chargement complexe. Dans un formalisme thermodynamique, ce processus nonlinéaire peut être décrit de manière continue par une variable d’endommagement…

CFD Modelling for the Design of a Photovoltaic-Thermal Solar Panel Dedicated to Solar-Assisted Heat Pump

A two-dimensional heat diffusion problem with a heat source that is a quasilinear parabolic problem is examined analytically and numerically. Periodic boundary conditions are employed. As the problem is nonlinear, Picard’s successive approximation…
