Abstract

The present paper aims to present a parametrical analysis from polygonal tubes under dynamical compressive loads, representing an impact collision between a barrier and an impact absorber. The finite element simulations are performed for quadrilateral and hexagonal cross sections, considering solid standard tubes as well as tubes with openings in their side walls, the so called windowed tubes. The parametric analysis asses the total absorbed energy, the specific energy absorbed (SEA) in addition to the initial peak load.
