  Thesis title: The development of a consistent method to study residual stress effects on fatigue crack growth Summary: During this thesis my main focus was to develop a method to introduce residual stresses into laboratory coupons in a consistent way, such that crack growth tests could be performed on these coupons. By comparing crack growth data from the stress-free and stress-induced coupons, residual stress effect could be observed. Crack growth predictions were made in two ways. The first was the classical weight function method and the second was by Finite Elements (Abaqus). Both predictions agreed very well to the test data at three different stress ratios (R=-1, R=0.05 & R=0.7). Rectangular 7050 aluminum coupons were milled from a large plate and four-point-bent into the plastic domain to consistently introduce residual stresses in the coupons. Strains were measured by DIC and strain gauges and were translated to stresses by the full stress-strain curve. Stress-strain curves were determined in both tension and compression by using dog-bone and cylindrical specimens respectively. By knowing the residual stress distribution in every coupon, residual stress intensity factors were calculated by using a weight function and by using the J-integral in the FEM. Those K-solutions were superimposed to the applied stress intensity factors to take residual stress effects into account. Crack growth tests were performed in the Single Edge Notch tension configuration on a closed loop servohydraulic MTS fatigue machine. THe crack growth predictions were within a growth rate factor 2 for all coupons over three decades of range. Show less
