Specimen Inertia in high strain rate tensile testing
EPJ Web of Conferences, 2015 It is well established that measurements of the dynamic mechanical response of materials are susceptible to errors due to the inertia of the specimen, which causes stresses in addition to the intrinsic material strength.

Mechanical behavior of sand under high pressure and high strain rate
EPJ Web of Conferences, 2012 Characterizing of the mechanical behavior of sand under impact loading is necessary to estimate the power of explosive mines. Using Hopkinson pressure bars for its characterization only low and limited pressures can be applied.

Image-based high strain rate testing of orthopaedic bone cement
EPJ Web of Conferences, 2018 Bone cement is widely used for the fixation of orthopaedic implants. It is a multi-component material that consists of a PMMA base with a small proportion of (usually ceramic) radiopacifier to enable the cement to be observed by X-ray.

High strain rate compression of epoxy micropillars [PDF]
Extreme Mechanics Letters, 2020 The study of the high strain rate mechanical behaviour of materials using micropillar compression tests has been hindered so far due to the lack of suitable instrumentation. In the present study, a novel high strain rate micropillar compression set-up is introduced.
