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.

Moreover, the equation proposed by Reese and O'' Neil correlates better with the above mentioned recommendations. In all cases, according to Ostermayer H. and Barley T. [6], for bonded lengths more than 6m, the progressive debonding phenomenon should be taken into account and the recommended values should be reduced accordingly.
