### A bonded-particle model for rock

· (A contact bond provides tensile and shear strengths only and behaves like a parallel bond with k ¯ n = k ¯ s = R ¯ = 0.) In that work, a time-dependent strength-degradation process was included in the simplified BPM by reducing the contact-bond strength at a specified rate if the contact force was above a specified microactivation force.
