July 1978 On the measurement of residual-stress gradients in-alloy specimens The modified hole-drilling technique is extended to the measurement of biaxial residual-stress gradients induced by edge-dimpling technique in 2024-T3
Based on developed reliable prediction models, NSGA-II is further applied to multiobjective optimal design of aluminium alloys in a fashion. It is revealed that optimal machining regimes to minimize residual stress and
Residual stress distributions of the CRDM penetration nozzles were estimated for an operating NPP. The residual stress values were dependent on the inclination angle and welded zone, and the hoop stress at up-hill weld toe region was the maximum,
The residual stresses in heat treated 7075 aluminium alloy blocks have been characterised using two neutron diffraction strain scanning instruments. The influence of uniaxial cold compression on relieving the residual stress has been determined. Increasing
After this static analysis is performed, a stable residual stress and spring-back deformation field will be obtained ready for the final stage, in which the related residual stresses and plastically affected depth can be determined. 3. Metal alloy rods with
