摘要

This paper proposes a new strategy to simulate or predict the propagation of cohesive cracks under mode-I loading by Vector Form Intrinsic Finite Element (VFIFE) method. The VFIFE method is based on the theory of vector mechanics, which simulates continuous body by mass particles, and thus converts the issue of body defamation into particle motion. This unique characteristic enables VFIFE to easily handle the problems of the large deformation, large displacement and fracture without the global stiffness matrices and the extra weak stiffness element. In this paper, the cohesive crack propagation is simulated by combining the VFIFE method and Fictitious Crack Model (FCM). The crack propagation of a three-point bending beam is simulated, and comparison of the calculated loaddisplacement curves with those obtained by other numerical studies has validated the effectiveness of the present VFIFE-FCM method for simulation of crack propagation.
