Description

A method to optimize structural parameters of a material is here presented, so as to insure the best protection against an external impulse. Projection on the basis of the structure's natural modes allows to reduce the study of stresses on the whole to superposition of stresses provided by each mode. An energy calculus per mode leads to define their respective risks, to ascertain the influence of parameters to be optimized and consequently to define these parameters

Abstract (French)

Nous presentons dans cette etude une methode d'optimisation de parametres de structuration d'un materiau afin de le proteger au maximum d'une agression exterieure de nature impulsionnelle. La projection sur la base des modes propres de la structure permet de ramener l'etude des sollicitations globales a la superposition des sollicitations apportees par chaque mode. Un calcul energetique par mode permet de determiner leurs dangers respectifs et de connaitre l'influence des parametres a optimiser et de les definir en consequence
