The light-weight aluminium alloys play an important role in reducing emissions from the transport industry. However, to take full advantage of these, corrosion mechanisms that govern their failure need be properly understood. Hence, electrochemical response, especially after passive film breakdown, alloy AA5083 was analysed via potentiodynamic polarisation. By starting scans at relatively negat...

Finite element method (FEM) suffers from a serious mesh distortion problem when used for high velocity impact analyses. The smooth particle hydrodynamics (SPH) method is appropriate for this class of problems involving severe damages but at considerable computational cost. It is beneficial if the latter is adopted only in severely distorted regions and FEM further away. The coupled smooth parti...

The joining of dissimilar 6mm thickness plates AA6082 & AA5083 was carried out using the friction stir welding (FSW) technique. process parameters are optimized Taguchi L9 orthogonal design experiments. Where rotational speed (600, 900, 1200 rpm), travel (60, 90, 120 mm/min), and tilt angle (0, 1, 2◦ ) were taken into consideration. optimum determined with reference to tensile strength, yield s...
