Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
, 2007 We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Numerical simulation of jointed rock mass blasting under different in-situ stress conditions
工程科学学报, 2016 Two-hole blasting of jointed rock mass under different in-situ stress conditions(lateral pressure coefficient:0.5,1 and 2; vertical stress:5 MPa and 10 MPa) and joint angles(30°,45°,60° and 90°) was numerically simulated to study the ...

Crack propagation in honeycomb cellular materials: a computational approach [PDF]
, 2012 Computational models based on the finite element method and linear or nonlinear fracture mechanics are herein proposed to study the mechanical response of functionally designed cellular components. It is demonstrated that, via a suitable tailoring of the

Simulation of fatigue behaviour in fusion welded 2024-T351 [PDF]
, 2004 A model has been developed to predict short crack fatigue life in the fusion zone of Metal Inert Gas (MIG) welded 2024-T351, based on the observed propensity for complex, multiple cracking processes in this region.

Quasi-static crack propagation by Griffith's criterion [PDF]
, 2008 We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith's criterion in a suitable form
