Mixed mode fracture resistance data set from DCB-UBM experiments

The present repository contains an extensive data set of mixed-mode fracture resistance curves extracted from a series of 45 double cantilever beams under uneven bending moment experiments. The data will be further explained in a Data in Brief paper which has been sent for review. The title of the submitted article is "Dataset of mixed-mode R-curves from DCB-UBM fracture tests of a UD glass/epoxy composite" and it is submitted as an accompanying article to the already published work: Erives, R., Sørensen, B. F., & Goutianos, S. (2022). Extraction of mix-mode cohesive laws of a unidirectional composite undergoing delamination with large-scale fibre bridging.
