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: R.K.
