The forming parameters for incremental forming of aluminium alloy 3003 sheet are presented. Using two shapes for testing (a conical shape and a pyramid shape) and forming the sheet to various draft angles, the following data have been assembled: tensile tests, strain measurements, strength coefficient K and strain-hardening exponent n. The method of analysis of stress-strain diagrams used by Ford in the plane strain compression test are shown to be applicable. Relationships such as the sine law for spinning have been applied to the data and are presented.

Laser Shock Wave

The large area delaminated (two layers) and non-delaminated samples of 1mm-thick aluminium alloy 2024 were shocked by pulse laser, the restricted layer and the absorbing layer were coated on the surface of the samples, and the PVDF sensors were set on the facing of a quilt of the samples. The signs of laser shock waves were transmitted to the computer by the oscillograph. The results indicated that can be effective detected by laser shock waves, and the math model of hierarchical sheet-metal by laser shock wave was fundamentally developed. A new method to detect the large area delaminated samples was provided, which has the definite engineering importance.

In the bringout research work carried out the comparative study of weld characteristics of Aluminium Alloy AA2014-T6 weldments, joined by employing two processes namely Friction Stir Welding (FSW) and Gas Tungsten Arc Welding (GTAW). FSW was performed with three different geometrical tool pin profiles like triangular, square, pentagon with process variables like tool rotational speed of 1400rpm, traverse speed of 86mm/min and tool tilt angle 3⁰. GTAW process was carried out by using constant current welding (CCW) and pulse current welding (PCW) at a frequencies of 2Hz and 4Hz respectively. This work lead to study the Ultimate Tensile Strength (UTS), 0.2%Yield Strength (YS) and % Elongation (%El) of AA2014-T6 weldments produced by FSW and GTAW
