Abstract : This study addresses the development of the Surface-Integral and Finite Element ((SAFE) hybrid method for the analysis of short or physically small cracks. In this report, a brief review of representative research papers on fracture mechanics of short cracks is provided. The development of the SAFE hybrid method for materially nonlinear analysis is discussed. Motivation for the use of lumped plasticity models via modelling shear bands at the crack tip is given. Work in progress and future research tasks to be performed under this contract are outlined. Keywords: Fracture; Short cracks, Finite element; Integral equation; Fatigue(Mechanics).
