Abstract
Experimental investigations have been carried out to study the effect of specimen configuration and loading history on the crack growth beha viour of 2024-T3 aluminium alloy at room temperature. It has been obse rved that fatigue crack growth rate in specimens loaded symmetrically is higher than that in specimens loaded asymmetrically. Further it has been observed that the crack growth rate under increasing stress inte nsity factor (SIF) range is higher than that under decreasing SIF rang e. These observations have been attributed to stress distribution ahea d of the crack and the residual stresses developed during loading.
