A simple procedure for determining the mode I bridging stress of composite DCB laminates without measuring the crack opening displacement

Fiber bridging usually presents in the wake of crack tip in delamination tests of composite double cantilever beam (DCB) specimens. An effective method determining the bridging law is required, which can be applied for developing accurate prediction model. However, extracting the bridging law in the fiber bridging zone is difficult. Here, a simple procedure is proposed for the determination of mode I bridging law. The crack opening displacement...
