What does LEFM stand for?

Based on Griffith criterion, when the crack propagation behavior sufficiently satisfies linear elastic fracture mechanics (LEFM) conditions, the slow crack growth resistance is directly related to elastic fracture toughness of the material.

Numerical analysis is conducted by the boundary element method (BEM) based on the concept of linear elastic fracture mechanics (LEFM) to clarify the mechanisms of corrosion-induced crack extension.

Otherwise, the structure of the work has remain unchanged with chapters discussing fundamental concepts related to linear elastic fracture mechanics, elastic- plastic fracture mechanics, and dynamic and time-dependent fracture; fracture mechanisms in metals and nonmetals; and applications such as fracture toughness testing of metals, fracture testing of nonmetals, application to structures, fatigue crack propagation, and computational fracture mechanics.

Numerical analysis Linear elastic fracture mechanics (LEFM) allows the stress to approach infinity at a crack tip.

Principles of linear elastic fracture mechanics are employed to provide data for strength analysis of cracked or flawed structures, or components.

This model gives, by analogy with the Linear Elastic Fracture Mechanics (LEFM), an expression of J under a simple form.

Last but not least, polyethylene displays, in the short term, a highly ductile behavior, out of reach of usual linear elastic fracture mechanics concepts and methods.

Nonlinear, viscoelastic, craze-forming materials such as PE present a severe challenge to the Linear Elastic Fracture Mechanics (LEFM) principles on which this method is based (10).
