Part 4 Modeling delamination: Predicting progressive delamination via interface elements; Competing cohesive layer models for prediction of delamination growth; Modeling of delamination fracture in composites: A review; Delamination in adhesively bonded joints; Delamination propagation under cyclic loading; Single and multiple delamination in the presence of nonlinear crack face mechanisms. Part 5 Analysis of structural performance in presence of delamination and prevention/mitigation of delamination: Determination of delamination damage in composites under impact loads; Delamination buckling of composite cylindrical shells; Delamination failure under compression of composite laminates and sandwich structures; Self-healing composites; Z-pin bridging in composite delamination; Delamination suppression at ply drops by ply chamfering; Influence of resin on delamination.

Given such advantages as low weight compared to strength and toughness, laminated composites are now used in a wide range of applications. Their increasing use has underlined the need to understand their principal mode of failure, delamination. This important book reviews key research in understanding and preventing delamination.

The first part of the book reviews general issues such as the role of fracture mechanics in understanding delamination, design issues and ways of testing delamination resistance. Part two describes techniques for detecting and characterising delamination such as piezoelectric sensors, the use of lamb waves and acoustic emission techniques. The next two sections of the book discuss ways of studying and modelling delamination behaviour. The final part of the book reviews research on delamination behaviour in particular conditions such as shell and sandwich structures, z-pin bridging and resin bonding.

With its distinguished editor and international team of contributors, Delamination behaviour of composites is a standard reference for all those researching laminated composites and using them in such diverse applications as microelectronics, aerospace, marine, automotive and civil engineering.
