Asymmetric four-point bend test
This video shows the evolution of principal strain during a 4-point asymmetric bend test. The position of rollers allows for the introduction of mixing modes of loading (Mode I and Mode II). The test validated a damage model based on the Modified Mohr-Coulomb criterion. Details of the model can be found at: https://doi.org/10.1016/j.tafmec.2022...
