ABSTRACT

This paper describes the large deformation phenomenon and compares the plastic energy absorption of tubes, for the different phenomenon. Experiments were conducted on circular aluminum tubes having typical external diameter of 25.5 mm and thickness 2 mm. Generally the tube lengths were 100mm. Also 50mm lengths were chosen to see the length effect on the deformation phenomenon. Numerical analysis was performed to simulate the different phenomenon. A good agreement was observed between experimental data and numerical simulation. The force-stroke curves of different deformation modes are discussed in detail. Various characteristics associated with large deformation are explored and discussed. Based on these experimental studies, best energy absorption phenomenon is found.

Keywords: Large deformations, fixtures, energy absorption, plastic deformation, force-stroke
