WebIn simulating discontinuities such as cracks, a derivative-free continuum theory – peridynamics, to wit – has an advantage in that the integro-differential balance laws work even with discontinuities. It does not need the special measures required with continuum models using partial differential equations (PDEs) for simulating cracks. WebDec 9, 2010 · A methodology is presented for investigating the dynamics of heterogeneous media using the nonlocal continuum model given by the peridynamic formulation. The approach presented here provides the ability to model the macroscopic dynamics while at the same time resolving the dynamics at the length scales of the microstructure. how often change spa water
