This paper investigates the bending and wear behaviour of hollow aluminium alloy pipes of circular cross section. Three-point bending tests were conducted at different strain rates (0.001, 0.01, and 0.1 s−1) and span lengths (100, 120, and 140 mm) on universal testing machine to understand the bending behaviour of the hollow pipes. The wear behaviour of the pipes was analysed under three different loads (30, 40, and 50 N) and speeds (200, 300, and 400 rpm) on pin-on-disc machine. It is found that the bending strength of the pipe is sensitive to the strain rate and the specimen geometry. Also, the wear and friction characteristics of the circular pipe change with varying loads and speeds.

摘要

This paper investigates the bending and wear behaviour of hollow aluminium alloy pipes of circular cross section. Three-point bending tests were conducted at different strain rates (0.001, 0.01, and 0.1 s−1) and span lengths (100, 120, and 140 mm) on universal testing machine to understand the bending behaviour of the hollow pipes. The wear behaviour of the pipes was analysed under three different loads (30, 40, and 50 N) and speeds (200, 300, and 400 rpm) on pin-on-disc machine. It is found that the bending strength of the pipe is sensitive to the strain rate and the specimen geometry. Also, the wear and friction characteristics of the circular pipe change with varying loads and speeds.
