dc.description.abstractAn evaluation of the smeared crack representation of material failure using the material-point method (MPM) as a feasible computational failure approach is performed. The spatial descretization in MPM is defined by a grid of cells that represent space and a set of points that represent the deformable solid. A grid orientation bias in the numerical results is demonstrated. Solution accuracy is lost when failure surface and grid line orientations are not aligned. Causes of the grid orientation dependence are identified, but the problem remains unresolved. Limited use of the smeared crack approach in MPM for solving problems of material failure is advised.en_US
