Numerical Modelling of a Chevron Notched Bend Specimen - Plane Model

The paper focuses on a numerical modelling of the initial chevron notch in test specimens subjected to the three-point bending test geometry configuration. The plane model is used with variable thicknesses of the layers with plane stress condition. The number of layers is being investigated and the influence of some input parameters like relative crack length, breadth of initial notch, etc. is evaluated by value of the stress intensity factor for tension loading mode.
