Abstract
- A nonlocal algorithm is used to control the failure propagation rate in finite element simulations. An extension of the method, which creates smooth gradient fields near the fracture front, is explored as a means for improving the advection of discontinuous fields associated with cracks. The algorithms are evaluated by varying fracture propagation speed and assessing crack size changes with advection.<br />The original document contains color images.
