Theoretical and numerical investigation of mode‐I delamination of composite double‐cantilever beam with partially reinforced arms

In this paper, a theoretical analysis model and two simulation methods are applied to characterize the quasi‐static and fatigue delamination of composite double‐cantilever beam (DCB) with partially reinforced arms. The test data of partially reinforced DCB were used as benchmark to verify the analysis model and simulation, and cohesive zone models (CZMs) and virtual crack closure technique (VCCT) are used in simulation. It is shown that the...
