The Mechanics of Threaded Fasteners and Bolted Joints for Engineering and Design

The Mechanics of Threaded Fasteners and Bolted Joints discusses how threaded fasteners and bolted joints fail, how to remedy these failures, and how to avoid them through tightening methods, material strength, and avoiding loosening. It also covers bolt force variation due to elastic interaction and the separation of the plate interface via increased external force as the primary cause of fatigue failure.

Threaded fasteners and bolted joints are essential components in various industries, but their failure mechanisms and prevention strategies are crucial to ensure the safety and reliability of structures. The Mechanics of Threaded Fasteners and Bolted Joints provides a comprehensive overview of these mechanisms, their causes, and potential remedies.

The book begins by explaining how threaded fasteners and bolted joints fail, including factors such as thread misalignment, improper installation, and excessive loads. It then delves into the various methods used to prevent these failures, such as tightening methods, material strength, and proper maintenance.

One of the key aspects of threaded fasteners and bolted joints is selecting the appropriate tightening method. The book discusses the different types of tightening methods, including torque, tension, and preload, and explains how to determine the optimal tightening procedure for varying nominal diameters. It also highlights the importance of using proper tools and techniques to ensure accurate and consistent tightening.

Using the finite element method, the book demonstrates the characteristics of stress concentration and fatigue strength in threaded fasteners. It explains how bolt force variation due to elastic interaction can affect the performance of these joints and provides effective countermeasures to mitigate these effects.

The book also discusses the primary cause of fatigue failure in threaded fasteners, which is the separation of the plate interface via increased external force. It provides practical solutions for preventing this failure, such as using proper surface finishes, applying appropriate lubricants, and ensuring proper installation techniques.

In addition to theoretical discussions, the book includes empirical equations of thermal contact coefficient and apparent thermal contact coefficient in simple form. These equations are useful for designing and analyzing threaded fasteners and bolted joints in thermal environments.

Overall, The Mechanics of Threaded Fasteners and Bolted Joints is a valuable resource for engineers, technicians, and professionals involved in the design, installation, and maintenance of threaded fasteners and bolted joints. It provides a comprehensive understanding of these mechanisms, their causes, and potential remedies, and helps practitioners ensure the safety and reliability of their structures.
