Abstract
Over the past many decades, numerous research efforts have been directed to overcome the major challenge of automotive and aeronautical industries to design lightweight and crash-worthy vehicles that are subjected to impact loading. The energy absorbers are provided in the automobiles and aircraft to minimize the damage to occupants and main structural part of vehicle itself. Many energy-absorbing devices could be appropriately designed for the transport vehicles, however, the thin-walled tubular structures have been widely employed to reduce the destructive effects of dynamic impact loading during a collision and thus increase the crashworthiness behavior of the structural frame. A comprehensive knowledge of the structural performance and material properties of various thin-walled structures under different dynamic loading conditions is important for designing a perfect energy-absorbing device. In this paper, based on a detailed literature survey, a comprehensive overview of the recent investigations in the area of crashworthiness behavior of thin-walled tubes is specified on the topics that appeared in the last decade such as optimization for crashworthiness and energy absorbing performance of unconventional thin-walled components including functionally graded thickness tubes and multi-cell tubes. Due to a large number of studies that analyzed and evaluated the energy absorption behavior of various thin wall structures, this paper presents only an overview on crashworthiness response of the structural components that can be used in vehicular structures including multi-cell thin-walled tubes under axial, oblique and bending loading.
