Description

PASTEL is a finite element code for structural analysis. It involves a number of calculations for structures consisting in various materials and element assemblies; the whole being however described in a two-dimensional geometry (planar and revolution structures) PASTEL is especially suitable for computing the stresses in the materials constituting nuclear reactor cores. Indeed, it may take into account: the dimensional variations of materials as well as their stiffness as functions of dose, temperature, plasticity, creep laws, and the loading variations and temporal temperature charts. PASTEL can be used for eigenmode analysis and dynamic computations

Abstract (French)

PASTEL est un code de calcul de structures base sur la methode des elements finis. Il effectue un certain nombre de calculs sur des structures composees d'assemblages de materiaux et d'elements differents; l'ensemble etant toutefois decrit dans une geometrie a deux dimensions (structures planes ou de revolution). PASTEL est particulierement bien adapte au calcul de l'evolution des contraintes dans les materiaux constituant les coeurs des reacteurs nucleaires. Il peut en effet tenir compte: des variations dimensionnelles des materiaux ainsi que de leur rigidite en fonction de la dose et de la temperature, de la plasticite, des lois de fluage, et de la variation du chargement et des cartes de temperature au cours du temps. PASTEL peut egalement effectuer des recherches de modes propres et des calculs dynamiques
