OSTI ID:5229897
A numerical analysis of cemented granular material has been performed in order to better understand the relationship between the individual components of a rock matrix and the macroscopic constitutive response. A distinct element code was modified to allow interparticle bonding by incorporating appropriate elastic relationships. A modified Griffith criterion was utilized to initiate fracture within individual bonds. A number of quasi-static and dynamic numerical experiments are presented which show that realistic macroscopic behavior may be obtained without the use of phenomenological formulations such as plasticity. 9 refs., 17 figs.
