Review of the crushing response of collapsible tubular structures

Vivek PATEL, Gaurav TIWARI, Ravikumar DUMPALA

《机械工程前沿（英文）》 2020年第15卷第3期页码 438-474 doi: 10.1007/s11465-019-0579-1

摘要： Studies on determining and analyzing the crushing response of tubular structures are of significant interest, primarily due to their relation to safety. Several aspects of tubular structures, such as geometry, material, configuration, and hybrid structure, have been used as criteria for evaluation. In this review, a comprehensive analysis of the important findings of extensive research on understanding the crushing response of thin-walled tubular structures is presented. Advancements in thin-walled structures, including multi-cell tube, honeycomb and foam-filled, multi wall, and functionally graded thickness tubes, are also discussed, focusing on their energy absorption ability. An extensive review of experimentation and numerical analysis used to extract the deformation behavior of materials, such as aluminum and steel, against static and dynamic loadings are also provided. Several tube shapes, such as tubes of uniform and nonuniform (tapered) cross sections of circular, square, and rectangular shapes, have been used in different studies to identify their efficacy. Apart from geometric and loading parameters, the effects of fabrication process, heat treatment, and triggering mechanism on initiating plastic deformation, such as cutouts and grooves, on the surface of tubular structures are discussed.

摘要：

跌落冲击是物体在短时间内受到强大冲击力而运动状态发生急剧变化的现象，是导致产品特别是小型机电产品外表破损、功能失效的主要原因。近年来，国内外研究学者针对如何提高产品抗跌落冲击的本质耐撞性能进行了大量研究。笔者从研究对象、研究方法等角度，系统总结了产品跌落冲击耐撞性和产品耐撞性能稳健设计的研究现状，归纳了有待进一步研究的问题。
