Most scholars use the conventional formula provided by the standard to estimate the strain energy release rate (G Ic ), and only use acoustic emission as a tool to describe the delamination process of composite laminates rather than a research method to predict delamination damage of composite laminates. Combining the strain energy release rate test using a double cantilever beam (DCB) with real-time acoustic emission monitoring can provide relevant information about the progressive damage evolution process of delamination of composite laminates.
