A mixed mode cohesive model for FRP laminates incorporating large scale bridging behaviour - Datasets

This data upload includes the experimental results from delaminating FRP-laminates. The experiment consists of DCB specimens where the beam ends are loaded with bending moments. A set-up of LVDTs and a clip-on extensometer are used to calculate the normal and tangential opening displacements at the crack-end.

The test specimens are described in the file "CHO test matrix 130405B.xlsx"

The load-displacement data for all specimens are given in the folder "DCB UBM - Experimental results.zip"

Acoustic emission recording from the tests are given in the folder "DCB UBM - Acoustic Emission.zip"

A set of images for each specimen during testing is given in the folder "DCB Images.zip"

This test series is examined and described in the following peer reviewed papers:
