Determination of the Length Scale Parameter in Peridynamics
Abstract
Peridynamics is based on integro-differential equations and does not contain any spatial derivatives which makes it suitable for predicting failure initiation and propagation. It also has a length scale parameter called horizon, which gives peridynamics a non-local character. This research expanded the body of knowledge of research on Peridynamics by determining optimum horizon sizing for bond-based peridynamics, ordinary state-based peridynamics and non-ordinary state-based peridynamics. It introduces the use of a dual-horizon peridynamic framework for non-uniform discretization and variable horizon sizes and investigates aspects of non-local behavior. Further, this research extends Dual Horizon Peridynamics formulation to thermal diffusion analysis. Finally, the research introduced methods to handle cases with damage and reduce the computation time required to conduct peridynamic simulations. This research resulted in five peer reviewed journal with an additional four articles submitted for publication. This research was presented at nine technical conferences.
