Dataset of mixed-mode R-curves from DCB-UBM fracture tests of a UD glass/epoxy composite

An extensive dataset with mixed-mode fracture resistance experimental data (R-curves) and fracture process parameters is presented. The fracture resistance values are extracted from double cantilever beam specimens subject to un-even bending moments. The tested specimens are made of a unidirectional composite which undergoes large-scale fibre bridging during fracture. The data set contains both raw data (forces from two load-cells, time, acoustic emission signals, and opening displacement measurements) and processed data (J-integral, end-opening displacements, fracture process parameters) of each test. In the repository, MATLAB scripts are also provided to facilitate recreating the processed data from the raw data.
