Computational Contact Mechanics
Peter Wriggers,Giorgio Zavarise +1 more
TL;DR: The mathematical structure of the contact formulation for finite element methods is derived on the basis of a continuum description of contact, and several algorithms related to spatial contact search and fulfillment of the inequality constraints at the contact interface are discussed.

Extended finite element method for cohesive crack growth
Nicolas Moës,Ted Belytschko +1 more
TL;DR: In this article, an extended finite element method is applied to modeling growth of arbitrary cohesive cracks, which is governed by requiring the stress intensity factors at the tip of the cohesive zone to vanish.

Finite-deformation irreversible cohesive elements for three-dimensional crack-propagation analysis
Michael Ortiz,Anna Pandolfi +1 more
TL;DR: In this paper, a three-dimensional finite deformation cohesive element and a class of irreversible cohesive laws are proposed to track dynamic growing cracks in a drop-weight dynamic fracture test.

An engineering solution for mesh size effects in the simulation of delamination using cohesive zone models
TL;DR: In this paper, a methodology to determine the constitutive parameters for the simulation of progressive delamination is proposed, which accounts for the size of a cohesive finite element and the length of the cohesive zone to ensure the correct dissipation of energy.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.

Numerical simulations of fast crack growth in brittle solids
Xiaopeng Xu,Alan Needleman +1 more
TL;DR: In this article, a model of dynamic crack growth is presented for a plane strain block with an initial central crack subject to tensile loading, where crack branching emerges as a natural outcome of the initial-boundary value problem solution, without any ad hoc assumption regarding branching criteria.

Fracture Mechanics of Ceramics
TL;DR: In this article, a linear-elastic fracture mechanics can be applied to describe the failure behavior of small flaws in ceramic materials, which is caused by the extension of small faults.

Dynamic Fracture Mechanics

TL;DR: In this article, basic elastodynamic solutions for a stationary crack and asymptotic fields near a moving crack tip are presented. But they do not consider the elasticity and rate effects during crack growth.
