Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>The problems arising as a result of aging aircraft, rail and civil infrastructure have focused attention on tools for predicting the growth of cracks from small naturally occurring material discontinuities. To this end, the present paper discusses on the difference between the analysis tools needed for <italic>ab initio</italic> design and sustainment, modelling of cracks that grow from small naturally occurring material discontinuities and ways to determine the short crack d<italic>a</italic>/d<italic>N</italic> versus Δ<italic>K</italic> data from long crack American Society for Testing and Materials (ASTM) tests. It also discusses how existing equations can be used to predict short crack growth and how to account for the variations seen in crack growth histories. Attention is also focused on the recent Federal Aviation Administration limit of validity ruling and the effect of the environment on widespread fatigue damage in civil transport aircraft.</p> </abstract>
