Crack dynamics in a nonlinear lattice
International Journal of Fracture Mechanics - - 2006
A discrete two-dimensional square-cell lattice with a steady propagating crack is considered. The lattice particles are connected by massless bonds, which obey a piecewise-linear double- humped stress–strain relation. Initially, Hooke’s law is valid as the first stable branch of the force–elongation diagram; then, as the elongation becomes critical, the transition to the other branch occurs.

Cohesive crack models for semi-brittle materials derived from localization of damage coupled to plasticity
International Journal of Fracture Mechanics - Tập 69 - Trang 101-122 - 1994
Based on discontinuous displacement approximation of the continuum and ‘shear band’ kinematics, two cohesive crack models are derived within the constitutive framework of coupled damage and plasticity. The models employ the Rankine fracture criterion, and the model parameters are determined from a uniaxial tension test (mode I cracking). Bifurcation analysis is used in order to diagnose critical d...... hiện toàn bộ
Channel cracking during thermal cycling of thin film multi-layers
International Journal of Fracture Mechanics - Tập 119 - Trang 325-338 - 2003
This paper describes mechanisms that can lead to film channel cracking, even in scenarios when layer thickness is small. Computational models are used to illustrate conditions that lead to the introduction of channel cracks and their subsequent cycle- or time-dependent propagation. Results for elastic structures with periodic features are briefly reviewed to illustrate that small low-modulus secti...... hiện toàn bộ

Stress intensity factors for cracks emanating from rectangular cutouts
International Journal of Fracture Mechanics - Tập 6 - Trang 393-400 - 1970
The stress intensity factors are determined at the crack roots for a rectangular cutout with symmetric edge cracks in an infinite sheet under uniaxial tension. The stress analysis is carried out using conformal mapping and the Muskhelishvili formulation. Numerical results are obtained for varying crack length and selected length-to-width ratios for the rectangle. The stress intensity factors are c...... hiện toàn bộ
Dynamic crack response to a localized shear pulse perturbation in brittle amorphous materials: on crack surface roughening
International Journal of Fracture Mechanics - Tập 134 - Trang 1-22 - 2005
Linear Elastic Fracture Mechanics (LEFM) provides a coherent framework to evaluate quantitatively the energy flux released at the tip of a growing crack. However, the way in which the crack chooses its path in response to this energy flux remains far from completely understood: the growing crack creates a structure on its own as conveyed by crack surface roughening even in brittle amorphous materi...... hiện toàn bộ

Singularities near three-dimensional corners in composite laminates
International Journal of Fracture Mechanics - Tập 115 - Trang 361-375 - 2002
The high interlaminar stresses, which appear in laminated composites due to the boundary layer effect near the free edge, play an important role in the analysis and design of advanced structures. Moreover, they are also the dominant effect causing delamination. Even if the singular behavior of such structures is investigated in many works, most of them deal either with 2D, or with pseudo-3D proble...... hiện toàn bộ
The effect of a rigid elliptical inclusion on a straight crack
International Journal of Fracture Mechanics - Tập 46 - Trang 71-79 - 1990
The general problem of a straight crack near a rigid elliptical inclusion is solved. Complex potentials presented in a previous paper (Santare and Keer [6]) for the interaction of an edge dislocation with rigid ellipse are used to formulate the Green's function for this problem. The solution is written as a set of singular integral equations for crack opening displacement which are solved numerica...... hiện toàn bộ
