Energy Absorption of Thin-Walled Cylinders under Impact Load
Abstract
This paper aims to numerical study the impact behavior of steel thin-walled tubes with circular cross section. Finite element method (FEM) analysis is used to investigate the deformation behaviors under impact load. Here, ABAQUS/Explicit is applied to study mainly the effect of side wall curvature on the resistance strength of thin wall tube. In addition to, the effect tube wall thickness on the crushing behaviors are studied for different geometric patterns. The results shows the increase of tube side wall curvature tends to decrease the values of first peak loads, which help to control the crushing behaviors of the corrugated tubes in a good manner.
