Delamination initiation in fully clamped rectangular CFRP laminates subjected to out-of-plane quasi-static indentation loading

To further investigate the effects of in-plane and out-of-plane stresses on the delamination initiation for composite laminates under out-of-plane loading, this paper reports a joint experimental and numerical study, in which the fully clamped rectangular CFRP composite laminates were subjected to out-of-plane quasi-static indentations. The...

Influence of dislocations on the apparent elastic constants in single metallic crystallites: an analytical approach

Intricate knowledge of dislocation networks in metals has proven paramount in understanding the constitutive behaviour of these materials but current experimental methods yield limited information on the characteristics of these networks. Recently, the isotropic anelastic response of metals has been used to investigate complex dislocation...

Role of adherend material on the fracture of bi-material composite bonded joints

The aim of this study is to investigate the effect of the adherend material on the mode I fracture behaviour of bi-material composite bonded joints. Both single-material (steel-steel and composite-composite) and bi-material (steel-composite) joints bonded with a structural epoxy adhesive are studied. Additionally, two adhesive bondline...

A static and free vibration analysis method for non-prismatic composite beams with a non-uniform flexible shear connection

Steel-concrete composite beams are widely used in practice because of their economic cross-section design. As sustainability becomes more and more important in the construction industry, the design of composite beams must be adapted to meet the requirements of the circular economy. This calls for demountability and reusability of the structural...

Directionality of damage growth in fibre metal laminates and hybrid structures

Fibre-metal laminates (FMLs) have been studied intensively for the past three decades because of their enhanced fatigue properties compared to monolithic metals. Most of these studies have focused on the fatigue damage under in-axis loading. These studies led to the application of FMLs in the aircraft structure in the early 21st century. However...
