An??lise em multi-escala do problema bidimensional de placas submetidas ao cisalhamento e considerando descolamento de fases

摘要

The present work deals with numerical analyses on mechanical behavior of ductile microstructures reinforced by elastic inclusions and the consequences upon micromechanical behavior of structures submitted to shear loadings. For this proposal, a proposed modeling based on computational homogenization technique using full coupling between scales and BEM/FEM is used. Also, the phase debonding is taken into account by using cohesive fracture and contact models where the opening sliding phenomenon is considered. On the other hand, the ductility of the metallic matrix is represented by Von Mises model. Initially, the numerical analyses are performed only at microstructural level and then a full coupled multi-scale analysis of a plate is considered, showing coherence between the micro and macro scale results.
