The Micromechanics of Fatigue Crack Initiation

  • Conference paper
Modelling Problems in Crack Tip Mechanics

Abstract

Over the last few years there has been an increasing interest in assessing the reliability of involved and expensive engineering structures and components being subjected to fatigue loading situations. The approach being taken in these studies has been and still is to describe, in a statistical manner, the microstructural material degradation processes taking place in polycrystalline materials and to infer from analytic, numeric and laboratory studies the reliability of the components and structures that utilize the materials in question prior to them leaving the design stage. The motivation behind these studies is to:

  1. (a)

    be in a position to supply to a prospective customer, definitive instructions as to safety, inspection intervals, spare part availability, life cycle costs, etc., and

  2. (b)

    be confident in these estimates based on accelerated and small scale laboratory testing and numerical algorithms.
