This paper presents an innovative methodology of material characterization under high strain rate (order 107s-1) laser shock loading coupled with microstructural and mechanical features. To that scope, experimental simulation analyses have been conducted for Al alloys (AA7075-T6 AA2017-T4) dissimilar Friction Stir Welded (FSWed) AA7075-AA2017 joint, pressure 4.5 GPa (laser power density 3.5 GW/...

Slow, intermediate and high strain rate experiments with UT geometries are performed on aluminum AA7075-T6 sheet metal at various temperatures. The comprehensive experimental program characterizes the plasticity response temperatures ranging from 20°C to 360°C rates 0.001/s 150/s. elevated temperature - a hydraulic tensile testing machine Split Hopkinson Pressure Bar system Load Inversion Devic...

The extrusion process of the belt is a in which and inner bore barrel undergo complex contact collision, rifling gradually penetrates belt, so that material continues to fail destroy. It has high instantaneous, strong impact, temperature, high-speed change. There big gap between existing theory actual process, it urgent carry out research work on this problem. This paper analyzes basic characte...
