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.

Mechanism of scaphoid waist fracture: finite element analysis

Journal of Hand Surgery (European Volume), 2022
The mechanism of scaphoid waist fracture is not completely understood. We used finite element analysis to study the formation of scaphoid waist fractures. Clinical computed tomography scans of 12 wrists were used to create models for finite element analysis.

Probabilistic Finite Element for Fracture Mechanics

HKIE Transactions, 2008
This paper presents a probabilistic methodology for fracture mechanics analysis of cracked structures. The main focus is on probabilistic aspect which related the nature of crack in material. The methodology involves finite element analysis; statistical models for uncertainty in material properties, crack size, fracture toughness and loads; and ...

Finite stress in fracture mechanics

Engineering Fracture Mechanics, 1994
Abstract The problem of implementing an essentially finite solution of the arbitrary boundary condition homogeneous medium mathematical rupture problem in terms of elasticity linear theory is discussed. The relevant concepts taken as a principle solution with the infinite strain values in rupture tips cannot be dealt with by damage mechanics.

Finite element methods in fracture mechanics

Computers & Structures, 1989
Finite-element methodology specific to the analysis of fracture mechanics problems is reviewed. Primary emphasis is on the important algorithmic developments which have enhanced the numerical modeling of fracture processes. Methodologies to address elastostatic problems in two and three dimensions, elastodynamic problems, elastoplastic problems ...
