Initiation, Growth, and Coalescence of Small Fatigue Cracks.

Abstract

This interim report summarizes the second year's progress on a research effort directed at studying the initiation, growth, and coalescence of small fatigue cracks at notches. A fracture mechanics based model is described to predict the growth and coalescence of multiple cracks located at notches. The predictive model is compared with experimental results obtained with multiple cracked specimens made from a transparent polymer and for metal specimens. Current efforts and future goals are also briefly described. (Author)
