Simulation of mode II unconstrained fracture path formation coupled with continuum anisotropic damage propagation in shale
The objective of this work is to simulate mode II multi-scale fracture propagation in shale by coupling a continuum anisotropic damage model with a Cohesive Zone Model (CZM). The Continuum Damage Mechanics – based Differential Stress Induced Damage (DSID) model is used to represent micro-scale crack evolution. DSID parameters were calibrated against pre-peak points of stress/strain curves obtai...
متن کاملPrediction of Mode II of Fracture Toughness in Laminate Composites
In this paper, effects of ply orientation of adjacent plies with (ϕ//θ) interfaces on mode II critical strain energy release rate (fracture toughness) of multidirectional (MD) laminate has been studied. Ply orientation of adjacent plies is one of the most important parameters affects the mode II critical strain energy release rate () in the initiation of the delamination. To study this paramet...
متن کاملInterlaminar Mode II Fracture Characterization
Delamination is an important concern in the context of structural behaviour of laminated composite materials. It is known that delamination can diminish the stiffness and the strength of the material and promote structural failure. Delamination onset and growth is governed by interlaminar fracture toughness of the material. Delamination propagation is frequently dominated by mode II fracture; c...
متن کاملDeveloping a Mode Ii Fracture Model for Composite Laminates
Delamination is a critical form of failure in composite laminates which is partitioned into a combination of three pure modes namely; opening, shearing and tearing (modes I, II and III respectively). Each fracture mode contributes to the total energy required for delamination growth, due to a combination of the different damage mechanisms that occur under each mode 1-2 . To formulate reliable m...
