Constant-probability crack growth curves
Date of Original Version
This paper details a stochastic, time-inhomogeneous model that serves as a theoretical basis for the prediction of crack growth and its variability under constant-amplitude loading. Crack evolution is described as a set of constant probability curves, each of whose points possess equal probability of advancing from one position to another forward position. This probability is governed by a transition intensity parameter for which two mathematical interpretations are examined. A simplified crack growth rate equation, employing one of the definitions, is derived and applied to A17075-T6 material for different loading conditions. Results of this application are compared with those experimentally obtained. © 1988.
