Abstract The Russian aggression in Ukraine, launched on 24 February 2022, marked the return of conventional war in the European continent. While Western leaders have framed the ongoing conflict through a common narrative when speaking internationally, which varies in its national nuances, much less is known about the images and lenses that the European

Franco‐British Bilateral Diplomacy After Brexit, 2020–2025: Mending the Ties That Bind
Abstract Brexit shook to its very core one of the European Union's (EU's) prominent partnerships, the Franco‐British bilateral relationship (FBBR), disrupting diplomatic routines and shattering interpersonal trust before circumstances changed and the relationship rapidly began to mend. In this article, we analyse the breakdown and restoration of Franco‐

Large-scale penetration test using a drop hammer
Rock Mechanics and Rock Engineering, 1997In the present study, large-scale penetration tests using a wedge-type drop hammer were performed. The primary objective was to determine the penetration curve in a large-scale test. The force-penetration curve is well known to be approximately linear in small-scale tests.

Hot Spot Formation in Mock Materials in Impact Sensitivity Testing by Drop Hammer
Propellants, Explosives, Pyrotechnics, 2017AbstractPowder and granulated sugars were exposed to the drop hammer impact test configured with 120‐ and 180‐grit Si/C sandpapers. The sugars were selected as mock materials for HMX (Octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine). The drop heights ranged from 24.2 to 40.7 cm.

Drop hammer tests of Scandinavian harness racetracks
Equine Veterinary Journal, 1994Summary Drop tests were carried out on 8 Scandinavian harness racetracks in order to evaluate their shock force attenuation properties. A drop hammer model was designed to simulate the hoof strike of the horse.

Improvement of Drop-Hammer Compression Test for Rubber Material
Materials Science Forum, 2011The drop-hammer compression testing method where the stroke is calculated by solving the equation of motions of the drop-hammer and anvil was improved in order to determine the strain-rate dependence of the elastic modulus of rubber material. An additional tool for interrupting the compression was embedded in the apparatus.

Multiple Reference Impact Testing for Bridge Assessment with Drop Hammer
Advanced Materials Research, 2012A new drop hammer was designed and used for multiple reference impact testing of two bridges. The drop hammer utilizes a multiple-rebound control system for successfully applying a single impact with repeatable high-level force for bridge testing. Signal analysis results indicate that the drop hammer provides a higher signal-noise ratio and a better ...
