ON A SIMPLE REPRESENTATION OF A FIBER-MATRIX INTERFACE WITH INITIALLY CLOSED CRACKS IN 3D STABILITY ANALYSIS

摘要

A simple model of a fiber-matrix interface with cracks in 3D stability analysis is discussed, in which a fiber-matrix interface is considered as a cylindrical surface with the possibility of sliding without friction. Due to 3D problem formulation the micromechanical modeling accounts explicitly for all six conditions at the interface in contrast to 2D and simpler models.
