Fragmentation of ice by low velocity impact [PDF]

, 1981
Low velocity impact experiments (0.14 to l km/s) carried out in polycrystalline water ice targets at 257 and 81 K resulted in interactions which can be assigned to four fragmentation classes, cratering, erosion, disruption, and total fragmentation ...

Simulations of dense granular gases without gravity with impact-velocity-dependent restitution coefficient [PDF]

, 2007
We report two-dimensional simulations of strongly vibrated granular materials without gravity. The coefficient of restitution depends on the impact velocity between particles by taking into account both the viscoelastic and plastic deformations of ...

Enhanced Infrared Image Processing for Impacted Carbon/Glass Fiber-Reinforced Composite Evaluation

Sensors, 2017
In this paper, an infrared pre-processing modality is presented. Different from a signal smoothing modality which only uses a polynomial fitting as the pre-processing method, the presented modality instead takes into account the low-order derivatives to ...

Quasi-static and low-velocity impact behavior of intraply hybrid flax/basalt composites [PDF]

, 2019
In an attempt to increase the low-velocity impact response of natural fiber composites, a new hybrid intraply woven fabric based on flax and basalt fibers has been used to manufacture laminates with both thermoplastic and thermoset matrices.
