This paper presents a new numerical approach to modelling rock fracture and fragmentation by combining the advantages of the mesh-free smoothed particle hydrodynamic (SPH) method with a new continuum constitutive model with embedded cohesive cracks. The new constitutive model is capable of providing the links of the continuum mechanics and the non-linear (decohesive) fracture mechanics. It will also possess an intrinsic length scale and hence can automatically capture size effects to produce mesh independent numerical solutions. The proposed numerical approach is illustrated at particle level to show essential features and advantages compared to traditional continuum based constitutive models in the context of SPH simulations.
