Recently, considerable research effort has been devoted to the fabrication of structures by adhesive bonding due to its definite advantages compared with other conventional techniques such as casting and welding. With bonding the need for stress relieving is avoided, the lead time is reduced and the design can be carried out according to optimum principles with the ability to bond different materials: for example, aluminium to steel, plastics to metals. These advantages have led to continuous efforts in studying the mechanism of bonding, in improving the properties of structural of adhesive...
