Shack-Hartmann wavefront sensing: A new approach to time-resolved measurement of stress intensity during dynamic fracture of small brittle specimens

Autor: Li, Liuchi, Kilic, Velat, Alemohammad, Milad, Ramesh, K. T., Foster, Mark A., Hufnagel, Todd C.

The stress intensity factor is important for understanding crack initiation and propagation. Because it cannot be measured directly, the characterization of the stress intensity factor relies on the measurement of deformation around a crack tip. Such

A predictive model for fluid-saturated, brittle granular materials during high-velocity impact events

Autor: Baumgarten, Aaron S., Moreno, Justin, Kuwik, Brett, Ghosh, Sohanjit, Hurley, Ryan, Ramesh, K. T.

Granular materials -- aggregates of many discrete, disconnected solid particles -- are ubiquitous in natural and industrial settings. Predictive models for their behavior have wide ranging applications, e.g. in defense, mining, construction, pharmace

While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional devastation. Several approaches have been proposed to potentially preven

Computational models of the human head are promising tools for estimating the impact-induced response of brain, and thus play an important role in the prediction of traumatic brain injury. Modern biofidelic head model simulations are associated with
