The fracture mechanics of finite crack extension

Engineering Fracture Mechanics, 2005
This paper describes a modification to the traditional Griffith energy balance as used in linear elastic fracture mechanics (LEFM). The modification involves using a finite amount of crack extension (Δa) instead of an infinitesimal extension (da) when calculating the energy release rate.

Analysis of Hertzian indentation fracture in the framework of finite fracture mechanics

International Journal of Fracture, 2017
The concept of finite fracture mechanics which assumes the spontaneous formation of a small, yet finite, crack and employs as stress-based as well as an energetic criterion is applied to the problem of indentation fracture initiation in brittle solids. In evaluating the energetic part of the fracture criterion a semi-analytical and a numerical approach,

Finite fracture mechanics: A coupled stress and energy failure criterion

Engineering Fracture Mechanics, 2006
The aim of the present paper is to introduce a new failure criterion in the framework of Finite Fracture Mechanics. Criteria assuming that failure of quasi-brittle materials is affected by stress or energy flux acting on a finite distance in front of the crack tip are widely used inside the scientific community.

Finite fracture mechanics analysis using the scaled boundary finite element method

Engineering Fracture Mechanics, 2015
The polygon-based scaled boundary finite element method is applied to two finite fracture mechanics based failure criteria to predict the crack initiation from stress concentrations, i.e. notches and holes. The stress and displacement fields are modelled
