Modeling of catastrophic disruption requires understanding the processes of dynamic failure and fragmentation. This paper summarizes current mechanisms and models for dynamic failure, strength, and fragmentation, reviewing these from a mechanics perspective and with an emphasis on making links to...

Tsui, Kwok Leung, Zuo, Ming J., Tse, Peter W., Wang, Dong
Gears are widely used in gearbox to transmit power from one shaft to another. Gear crack is one of the most frequent gear fault modes found in industry. Identification of different gear crack levels is beneficial in preventing any unexpected machine breakdown and reducing economic loss because...

Plescia, Jeffrey, Ramesh, K.T., Hogan, James, Kimberley, Jamie, Hazeli, Kavan
Knowledge of the relationships between microstructure, stress-state and failure mechanisms is important in the development and validation of numerical models simulating large-scale impact events. In this study, we investigate the effects of microstructural constituent phases and defects on the...

Carey, Jason P., Melenka, Garrett W., Schofield, Jonathon, Dawson, Michael R., Cheung, Benjamin O.
Three dimensional (3D) printing is a technique conventionally used to manufacture prototypes. Commercial desktop 3D printers have become available which produce functional 3D printed parts. The MarkOne by Mark Forged manufactures printed structures reinforced with continuous Carbon, Fiberglass or...

Ramesh, K., Farbaniec, Lukasz, Hogan, James D., Sano, Tomoko, Shaeffer, Matthew
This study investigates the effects of the processing-induced defect population on the dynamic compressive strength and failure of a hot-pressed boron carbide. Quantitative microscopic analysis was used to determine the distributions of three types of processing-induced inhomogeneities: aluminum...
