Opis

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 tubes
• Summarizes the mechanism of collapse and associated calculations for the initial peak force and the average compressive force
• Explores two factors controlling the axial collapse of a plate
• Investigates systematically the deformation characteristics of corrugated tubes under axial crush
• Provides an understanding of the collapse behavior of members undergoing bending deformation when trying to evaluate strength and energy-absorption characteristics
• Looks at the bending deformation of circular and square tubes
• Explains the characteristic flattening phenomenon, the maximum moment in bending deformation, and the moment-rotation relation during bending collapse
• Discusses the collapse behavior of thin-walled structures with an open cross section during axial crushing and bending deformation
• Includes the proposition of a new method for evaluating the maximum bending moment of square tubes with consideration of sidewall buckling
• Proposes a new technique that can be used to determine the relation between the bending moment M and the rotation angle
• Presents analysis methods for predicting the maximum torsion moment in each case

A 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."
