Dynamic rock tests using split Hopkinson (Kolsky) bar system – A review
Journal of Rock Mechanics and Geotechnical Engineering, 2015 Dynamic properties of rocks are important in a variety of rock mechanics and rock engineering problems. Due to the transient nature of the loading, dynamic tests of rock materials are very different from and much more challenging than their static ...

Using the split Hopkinson pressure bar to validate material models. [PDF]
Philos Trans A Math Phys Eng Sci, 2014 This paper gives a discussion of the use of the split-Hopkinson bar with particular reference to the requirements of materials modelling at QinetiQ. This is to deploy validated material models for numerical simulations that are physically based and have as little characterization overhead as possible.

Superior Impact-Resistant Composite Hydrogels Through an Ionic Coupling Strategy. [PDF]
Adv MaterAn ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,
