Abstract
In recent years, significant advances in computer hardware and software have impacted the ability to model and simulate dynamic fracture and damage processes. Eulerian, Lagrangian (finite element, meshless and various particle methods), and Arbitrary Lagrangian Eulerian techniques have been developed to simulate fracture growth and damage accumulation in conjunction with physics based free surface models such as the cohesive surface representation. Although the capabilities to calculate gross properties associated with the dynamic fracture and damage events have been obtained in a phenomenological sense, the ability to achieve predictive modeling of dynamic fracture and damage events has been elusive. Moreover, experimental data are required to validate numerical simulations. The purpose of this special session is to present recent progress in modeling and simulation of dynamic fracture and damage events. Both numerical and experimental advances will be included.
