内容説明

Redesigned for increased accessibility, this fourth edition of the bestselling Introduction to the Design and Behavior of Bolted Joints has been divided into two separate but complementary volumes. Each volume contains the basic information useful to bolting experts in any industry, but because the two volumes are more clearly focused, they are easier and more efficient to use. The first volume, Non-Gasketed Joints, describes the design, behavior, misbehavior, failure modes, and analysis of the bolts and bolted joints that play a large, even ubiquitous, role in the myriad machines and structures that form our world. The author elucidates why proper bolt tension - often called preload - is critical to the safety and reliability of an assembled joint. He introduces many ways to create that preload as well as ways to measure or inspect for it, then covers how to design joints that are less apt to misbehave or fail, using the guidelines, procedures, and simple algebraic mathematics included in the text. The book provides numerous tables, charts, graphs, and appendices, giving you all the information and data required to design and use non-gasketed bolted joints. Now leaner and meaner, this new edition is better suited for classrooms as well as the practicing engineer.
