Bolted joints Bolted joints play a vital role in the design and construction of fiber metal laminate (FML) composite structures. The behavior of these joints is dependent on a number of factors such as the geometry of the bolt, material behavior, layup sequence and load. This chapter is a thorough review of the existing literature and recent developments in the analyses of the behavior of bolted joints in FML composites. The influence of bolt diameter, distance between holes, distance between edges and plate thickness on the distribution of stress and the strength of the joint is discussed. The significance of load transfer and damage resistance of the joint according to layup sequencing and fiber orientation is brought out. The chapter also reflects the importance of bolt preload to joint integrity and the effects of environmental factors including temperature and humidity to the joint performance. The main failure modes that are witnessed in bolted FML joints, i.e., bearing, net-tension, and shear-out failure modes are outlined in more detail, and how each failure mode is transformable to the other depending on the geometry of the joint and material characterizations. The recent developments in numerical modeling methods including progressive damage analysis (PDA) and finite element modeling (FEM) are introduced demonstrating the accuracy in predicting joint strength and failure modes and damage progression. These models are validated against experimental data as well as their possibilities of optimizing the joint design. Future research directions have been presented and are based on the combination of state-of-the-art modeling methods with real-time monitoring and data-driven methods towards better joint reliability and performance in complex loading and environmental conditions. The chapter is a useful source of information to the researchers and engineers trying to design and analyze the FML composite structures involving bolted joints.
