  • Fatigue Properties : Part One
    Fatigue cracking is one of the primary damage mechanisms of structural components. Fatigue cracking results from cyclic stresses that are below the ultimate tensile stress, or even the yield stress of the material.
  • Fracture Toughness : Part Two
    For cases where the plastic energy at the crack tip is not negligible, other fracture mechanic models, such as the J integral or R-curve, can be used to characterize a material.
  • Linear Elastic Fracture Mechanics : Part One
    The theory of Linear Elastic Fracture Mechanics (LEFM) has been developed using a stress intensity factor (K) determined by the stress analysis, and expressed as a function of stress and crack size.
  • Zirconium Alloys: Part Two
    Research results have been used to determine the life of pressure tubes with regards to both crack initiation and subsequent DHC propagation.
