Residual Stress, Stress Relief, and Inhomogeneity in Aluminum Plate

Through-thickness residual-stress profiles in rolled 7050-T74 aluminum plate were measured before and after stress relief by stretching (-Tx51). Measurement required adapting the crack compliance method to measure both inplane stress components. Unexpected features in the profiles could be explained by through-thickness yield strength variations caused by crystallographic texture.

Residual Stresses in Butt and Socket Welded Joints

A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...

The effect of surface roughness on 1050 aluminum alloy weld profile welded by pulsed Nd:YAG laser

Surface roughness in the welding processes is one of the important parameters in the laser welded metal connections which affects laser beam absorption directly. When the laser beam is irradiated to the surface of the base metal, the surface roughness plays an important role in the amount of beam absorption and the amount of melting achieved and directly affects the penetration depth. The main ...
