Abstract

In this work, an anisotropic phase-field model (PFM) which is able to combine various damage initiation criteria is developed for the fracture analysis of thin fiber-reinforced composites. In order to prevent the unrealistic contribution of the fiber/matrix driving force to the failure of the matrix/fiber, two activation parameters are introduced in the crack driving force to determine the damage initiations of both the fiber and matrix, respectively. To improve computational efficiency and alleviate convergence difficulties, explicit time integration rules are adopted to solve the nonlinear governing equations. The present model is implemented in the finite element procedure ABAQUS through the user-defined element subroutine VUEL, and the efficiency of the present model is verified by the fracture analysis of unidirectional composite laminates. The predicted results agree well with the experimental and other numerical results reported in the literature. In addition, the necessity of separately introducing two activation parameters for fiber and matrix failure in the present phase-field model is investigated.

期刊介绍： Theoretical and Applied Fracture Mechanics'' aims & scopes have been re-designed to cover both the theoretical, applied, and numerical aspects associated with those cracking related phenomena taking place, at a micro-, meso-, and macroscopic level, in materials/components/structures of any kind. The journal aims to cover the cracking/mechanical behaviour of materials/components/structures in those situations involving both time-independent and time-dependent system of external forces/moments (such as, for instance, quasi-static, impulsive, impact, blasting, creep, contact, and fatigue loading). Since, under the above circumstances, the mechanical behaviour of cracked materials/components/structures is also affected by the environmental conditions, the journal would consider also those theoretical/experimental research works investigating the effect of external variables such as, for instance, the effect of corrosive environments as well as of high/low-temperature.
