Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TLDR
In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.About:

Cohesive Zone Models: A Critical Review of Traction-Separation Relationships Across Fracture Surfaces
TL;DR: In this article, potential-based models have been evaluated for mixed-mode cohesive fracture, and it is shown that these models lead to positive stiffness under certain separation paths, contrary to general cohesive fracture phenomena wherein the increase of separation generally results in the decrease of failure resistance across the fracture surface.

New crack-tip elements for XFEM and applications to cohesive cracks
Goangseup Zi,Ted Belytschko +1 more
TL;DR: In this article, an extended finite element method for a static cohesive crack is developed with a new formulation for elements containing crack tips, which can treat arbitrary cracks independent of the mesh and crack growth without remeshing.

Crack-Interface Grain Bridging as a Fracture Resistance I, Mechanism in Ceramics: I, Experimental Study on Alumina
TL;DR: In this paper, microscopic evidence is presented in support of an explanation of R-curve behavior in monophase ceramics by grain-localized bridging across the newly formed crack interface.
Journal ArticleDOI
Dynamic crack propagation based on loss of hyperbolicity and a new discontinuous enrichment
TL;DR: In this article, a methodology is developed for switching from a continuum to a discrete discontinuity where the governing partial dierential equation loses hyperbolicity, and the transition occurs on a set of measure zero.
Journal ArticleDOI
Statistical models of fracture
TL;DR: An overview of the results obtained with lattice models of the fracture, highlighting the relations with statistical physics theories and more conventional fracture mechanics approaches is presented.
