Structural Shear Joints

Part 1 Mechanical behaviour of shear joints and design considerations: Basic features; Shear joints in the bearing mode; Clamping, interference, micro-slip and self-piercing rivets; Fatigue of shear joints; Design considerations for repeated loading. Part 2 Compilation of finite element results: Load transfer in single rivet-row lap joints (conventional and countersunk); Compilation of results for open hole panels and butt joints; Compilation of results for lap joints; Single rivet-row lap joints under biaxial loading; Compilation of results for lap joints with sealants and adhesives; Compilation of results for rivets; Data tabulations. Part 3 Calculational models and validation: Finite element models; Thin adhesive layer analysis (TALA) for modeling sealants and adhesives installed in joints; Material models for finite element analysis and TALA; Validation for finite element models and TALA; Analysis for multiple – row joints and validation; Analysis of fastener tension and clamping strain.

Engineers employ shear connections - riveted and bolted butt and lap joints - in a wide range of structures and machines. Ordinary stress analysis of joints are unable to define the features that ultimately govern fatigue and fretting and provide bases for design. Detailed analysis has only become possible recently with advances in finite element methods and computing capabilities. This text places into context the results of over 150 detailed 2D and 3D finite element analyses of aluminum and steel shear connections so that engineers can optimise the design and reliability of shear joints.
