NOI VALENTE IN ANALIZA MULTISCALARA NELINIARA A STRUCTURILOR MECANICE FABRICATE DIN MATERIALE COMPOZITE

Autor/autori: Conf. dr. ing. Dana LUCA MOTOC

Rezumat: Lucrarea abordeaza cele mai importante aspecte care intervin in analiza multiscalara neliniara a structurilor mecanice fabricate din materiale compozite, in particular a unei bare de protectie pentru automobile. Aspectele identificate vizeaza in principal interdependenta dintre fenomenele de la nivel macro- si microscopic care influenteaza aspectele de proiectare asistata a etapelor de proiectare a structurii mecanice analizate.

Cuvinte cheie: analiza multiscalara neliniara, bara de protectie, material compozit.

Abstract: The herein paper approches the major phases specific to a nonlinear multi-scale process of composite material based mechanical structures, particular to automotive bumper beams. The phases identified and depicted will be close underlined to reveal interdependecies at scale transition from macro to micro in the CAD analysis of the mechanical structure under study.

Keywords: nonlinear multiscale analysis, bumper, composite.
