Abstract
In the present research work, the fracture behaviour of a specific earthen material, that is, the shot-earth 772, is experimentally investigated. In particular, three-point bending tests on single edge-notched prismatic specimens of shot-earth are performed according to the RILEM Recommendations. Then, by exploiting the experimental results, the fracture toughness is analytically determined by means of the Modified Two-Parameter Model, which allows us to take into account the possible crack deflection, typically observed during the stable crack propagation in quasi-brittle materials.
