Fracture resistance dataset of composites under mixed-mode non-proportional loading

Abstract

Cohesive zone modelling is one of the main tools to simulate fracture of materials and structures. As a result a number of cohesive laws are being developed continuously. In most cases, due to experimental challenges, the response under mixed-mode fracture is assumed based on various models and it is unclear if fracture is path independent or not. In the co-submitted publication (Goutianos, 2021) it is shown, based on mixed mode fracture experiments under non-proportional loading, that for unidirectional composites path independence is to a large extent a reasonable assumption. The datasets of this publication are presented here with the aim to provide a set of experimental data, mixed-mode fracture under non-proportional loading, for testing the predictive capabilities of developed mixed-mode cohesive laws. The datasets include the raw mechanical data (force and end-opening displacement), analysed data (fracture resistance from the raw mechanical data), video recordings of the experiments and data from acoustic emission sensors.
