OSTI.GOV Book: Nonlinear fracture mechanics. Volume 2. Elastic-plastic fracture
In this video I present a basic look at the field of fracture mechanics, introducing the critical stress intensity factor, or fracture toughness.
The fracture of solids is analyzed using the formalism of equilibrium mechanics. A partially cracked, mechanically loaded reversible system is considered. A stability criteria is formulated. The equilibrium theory is valid for non-linear load deflection relationships and is applied to linear elastic fracture mechanics, the Hertz test and J IC tests.

Introduction: Linear Elastic Fracture Mechanics (LEFM) applies when the nonlinear deformation of the material is confined to a small region near the crack tip. For brittle materials, it accurately establishes the criteria for catastrophic failure.
Looking for abbreviations of NLFM? It is Non-Linear Fracture Mechanics. Non-Linear Fracture Mechanics listed as NLFM. The fracture analysis can be based on linear-elastic or more complex elastic–plastic (nonlinear) models.

The crack behaviour was analysed with nonlinear finite element analysis in Atena 2D. First, real experimental tie-rod tests were modelled with finite elements
It has been shown that the nonlinear behavior of concrete is related to its heterogeneity; the larger the grain size and the larger the volume fraction of inclusions, the more nonlinear and tougher is the observed behavior. In non-linear fracture mechanics (EPFM), an energy based criterion is used for assessing the risk for crack growth: if the energy release rate at the crack tip exceeds what is required for creating new surfaces in the material, crack growth will occur.
