Abstract

Composite laminate has wide usage in aerospace and automotive industry. Thus delamination, one of its most prevalent and challenging failure mode, has attracted substantial research effort, and lead to the rapid development of both simulation and experiment method. Although reviews exist about simulation and experiment method, there is not many that covers the development in most recent five years. This paper is targeted to fill that gap. We covered a broad range of topic in delamination, from the basic delamination onset and propagation theories to complex loading scenarios like impact and fatigue loading. From a simulation point of view, virtual crack closure technique (VCCT) and cohesive zone model (CZM), two most famous methods of delamination modeling, are compared and elaborated. Their implementation techniques are discussed, and we hope to give not only a description of the implementations but also their merits and drawbacks. We also covered the failure mode of combined delamination and matrix cracking, which is prevalent in impact loading scenario. Simulation techniques along with the failure mechanisms are presented. From experiment point of view, the discussed topics ranging from the basic delamination fracture toughness tests under static, dynamic or cyclic loading condition, to impact tests that aim to obtain the impact resistance and residual strength after impact. We hope to provide readers a useful collection of recent experiment data, and information about test method development.
