ESDU Analysis of Joints (Bolted, Bonded and Welded) Segment

This Segment gives comprehensive and continually expanding, rigorously evaluated information for the strength analysis of joints. Methods and data are given for static and fatigue strength calculations on bolted, bonded and welded joints and on lugs.

Data are given on stresses and strains under static loading. The fatigue data are principally for use when the design philosophy is one of "safe-life design", that is, the structure or component is required to be crack-free for the specified design life. The major part of the fatigue data consists of constant amplitude stress-endurance curves (S-N curves) for structural joints (riveted, bolted or welded) fabricated from aluminium or titanium alloy or steel.

The range of joint configurations and geometries gives a comprehensive selection that will meet the structural analyst's idealisation needs. Thus it will allow both detailed, accurate analyses of critical components, and initial estimates, with appropriate idealisation, that will facilitate the economic use of finite element or other expensive computational techniques on problems where no specific analysis is currently available.

The Analysis of Joints (Bolted, Bonded and Welded) Segment focuses on:
