Set-up of the mechanical test. (A) Overview of the specimen mounted in the testing machine, and (B) detail how the micrometric adjustable bidirectional slide allowed to apply the desired offset. The experimental testing sequence (C), which was replicated in all the different loading configurations, included a pre-conditioning and five repetitions of 6-cycle test. The red ellipses highlight the last cycle of each repetition, where the data were extracted and analysed. Figure published on Figshare (https://doi.org/10.6084/m9.figshare.25823887).
