Work of Fracture due to Compressive Component of Loading in Wedge Splitting Test on Quasi-Brittle Cementitious Specimens

Abstract:

The paper presents an analysis of the influence of the compressive (vertical) component of the loading force in the wedge splitting test on the values of fracture characteristics determined using standard procedures where this component is ignored. Particularly, a portion of work of fracture due to this compressive component of loading working on vertical displacements is investigated and given into relation with the common part of work of fracture calculated in the horizontal direction only. The results show that, based on the angle and width of the wedge used in the particular WST configuration, the portion of the work of fracture due to compressive loading can be considerable and should not be neglected.
