On the relevance of linear elastic fracture mechanics to ice
International Journal of Fracture, 1993A new criterion is proposed which allows one to estimate the minimum size for a brittle ice fracture specimen comprised of a small number of grains. According to this criterion, linear elastic fracture mechanics is a useful theory for fresh-water ice but may have limited use for saline ice.

Introduction to linear elastic fracture mechanics
2001Publisher Summary This chapter focuses on the concept of linear elastic fracture mechanics (LEFM). LEFM is the basic scheme used for most of the protocols. It has a secure theoretical basis in that all energy dissipation is associated with the fracture process and the deformation that occurs is linear elastic.

An introduction to fracture mechanics in linear elastic materials
Revue européenne de génie civil, 2007ABSTRACT This contribution introduces the basic concepts of Fracture Mechanics in linear elastic materials. A brief review of the history of Fracture Mechanics is given in the first section of the paper. Then we present the asymptotic behavior of the mechanical fields near the crack fronts.

Crack stability in linear elastic fracture mechanics
International Journal of Fracture Mechanics, 1969A linear elastic fracture mechanics analysis of the conditions that produce crack instability is presented. If the initial crack extension causes the change in crack-tip resistance to be negative with respect to the change in crack-tip loading, the crack will continue to propagate even though the loading agent remains stationary, and the crack is ...

Linear Elastic Fracture Mechanics (LEFM) and Applications
2001In brittle fracture it is assumed that failure in an elastic material takes place when the available elastic energy is adequate to overcome the energy necessary to propagate a crack and to create new crack surfaces. At the instant of instability, the stresses at the apex of an elastic crack must have sufficient magnitude, capable of driving the crack ...
