... and the analytical difficulties at the rupture tip of an interface (fault plane) in the proximity of a free surface. In this contribution, utilizing the techniques of finite difference modeling and dynamic photoelasticity, the fracture dynamics of a dip-slip fault plane located near a free surface is studied...

... Abstract A hybrid finite-discrete element method is introduced to simulate dynamic fracture of rock and resultant fragment arching caused by rock blast. Three typical examples, i.e. blast in a rock mass with a single borehole and a free surface, simultaneous blast, and consecutive blast...
