Following an outline of the full range of objectives of nonlinear fracture mechanics, the paper focuses on the phenomenological, or semiempirical, approach to the initiation of crack growth and the subsequent quasi-static crack growth and loss of stability under monotonic 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.

(2020) Discontinuum analysis of the fracture mechanism in masonry prisms and wallettes  CE597-176: Nonlinear Fracture Mechanics (Fall 2019) Description: This is a graduate course in Fracture Mechanics for those students who are interested in learning more about the concepts of material inelastic deformation and failure in the context of solid mechanics when cracks are present. fundamental concepts of elastic fracture mechanics before we look at nonlinear and complex behavior. The final part of the course will be based on projects where the student will be able to solve some open- 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.
