This chapter presents fracture mechanics based analysis and design of adhesively bonded structures. Common configurations and stress analysis characteristics of structural adhesive joints are introduced. Stress analysis and energy release rate based on a shear-lag model are firstly presented to show the importance of using fracture mechanics based design for structural adhesive joints. Modelling of adhesive joints and analytical stress analysis formulations are then derived to calculate energy release rates based on adhesive stresses; approaches to determine energy release rates based on the singular stress field and the beam theory are discussed. Finite element analysis based virtual crack closure technique and cohesive zone models to simulate progressive failure in adhesive joints are reviewed. Measurement of fracture toughness is discussed and determination of fracture parameters using state-of-the-art digital image correlation is presented.
