Inward Inversion Studies on the Stepped Shape Frusta

Inward Inversion Studies on the Stepped Shape Frusta This paper describes the plastic deformation and energy absorption of aluminum stepped geometry frusta, under axial compression between two flat plates. Experiments were carried out on aluminum frusta having stepped geometry. Geometrically these frusta were made with different diameter to thickness ratio at a height, different angle of steps & the thickness of frusta were also varied. Finite element (FE) analysis was carried out for experimental simulation. Deformation results and correlation from experiment and numerical simulations are discussed. Effect of various ratios like height to diameter, height to thickness, step geometry etc on deformation behavior, has been discussed in details, in this paper. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

This paper describes the plastic deformation and energy absorption of aluminum stepped geometry frusta, under axial compression between two flat plates. Experiments were carried out on aluminum frusta having stepped geometry. Geometrically these frusta were made with different diameter to thickness ratio at a height, different angle of steps & the thickness of frusta were also varied. Finite element (FE) analysis was carried out for experimental simulation. Deformation results and correlation from experiment and numerical simulations are discussed. Effect of various ratios like height to diameter, height to thickness, step geometry etc on deformation behavior, has been discussed in details, in this paper.
