CRC Press Crush Mechanics of Thin-Walled Tubes

Product Description Thin-walled structures can be used to absorb impact energy during a vehicle collision. Crush Mechanics of Thin-Walled Tubes describes the analysis and design of these lightweight elements and thoroughly explains the deformation behaviors of thin-walled hollow members under crushing loading. The book covers, in detail, thin-walled structures―under axial compression, bending, and torsion. It provides a complete understanding of the underlying concepts and mechanisms of energy absorption components, includes analysis techniques, and covers existing theoretical approaches along with the author’s research.Geared toward engineering students, practicing mechanical and structural engineers, and researchers interested in analyzing energy absorption and designing structures that may undergo impacts, this book:Addresses axial compression of circular and square tubes, and bending and torsion of tubesSummarizes the mechanism of collapse and associated calculations for the initial peak force and the average compressive forceExplores two factors controlling the axial collapse of a plateInvestigates systematically the deformation characteristics of corrugated tubes under axial crushProvides an understanding of the collapse behavior of members undergoing bending deformation when trying to evaluate strength and energy-absorption characteristicsLooks at the bending deformation of circular and square tubesExplains the characteristic flattening phenomenon, the maximum moment in bending deformation, and the moment-rotation relation during bending collapseDiscusses the collapse behavior of thin-walled structures with an open cross section during axial crushing and bending deformationIncludes the proposition of a new method for evaluating the maximum bending moment of square tubes with consideration of sidewall bucklingProposes a new technique that can be used to determine the relation between the bending moment M and the rotation angle θPresents analysis methods for predicting the maximum torsion moment in each caseA shelf-worthy reference showcasing structural mechanics, Crush Mechanics of Thin-Walled Tubes provides a basic understanding of the fundamental concepts and mechanisms of crushing deformations in thin-walled structures and serves as a guide for both teaching and self-study.
