Fracture mechanics is a failure theory that 1. determines material failure by energy criteria, possibly in conjunction with strength (or yield) criteria 2. considers failure to be propagating throughout the structure rather than simultaneous throughout the entire failure zone or surface.

The basis of a fracture mechanics safety analysis is the comparison between the crack driving force in a structure and the fracture toughness of the material evaluated in small scale tests. The application of one of the concepts depends on the overall behaviour of the structure which may be linear-elastic (K-concept) or elastic-plastic (CTOD- or J-Integral-concepts). About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators 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. However, severe limitations arise when large regions of the material are subject to plastic deformation before a crack propagates. The fracture analysis can be based on linear-elastic or more complex elastic–plastic (nonlinear) models. It is now well established that the nonlinear fracture-mechanics methods provide more realistic measures of fracture behavior of cracked structures with high toughness and low strength materials compared with the elastic methods.

Problems in Fracture Mechanics. PROBLEM: 1 If the specific surface energy for Polmethyl acrylate is 0.0365 J / m 2 and its corresponding modulus of elasticity is 2.38 GPa, compute the critical tensile stress required for unstable propagation of a central internal crack whose length is 30 mm. If the strength of the sound glass is 70 MPa, calculate the reduction in strength due to the presence

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.

Experimental Fracture Mechanics (EFM) is about the use and development of hardware and procedures, not only for crack detection, but, moreover, for the accurate determination of its geometry and loading conditions.
