Characterisation of dynamic behaviour of alumina ceramics: evaluation of stress uniformity [PDF]
AIP Advances, 2015 Accurate characterisation of dynamic behaviour of ceramics requires the reliable split-Hopkinson pressure bar (SHPB) technique and the condition of uniaxial homogeneous specimen deformation.

Split‐Hopkinson‐Pressure‐Bar simulations using MPM [PDF]
PAMM, 2021 AbstractThe material point method (MPM) represents a discretization method that combines the beneficial aspects of a Lagrangian representation of material within an Eulerian solution scheme. Deformable bodies are discretized with material points that carry mass, kinematical quantities such as velocity and material history variables. The material points

Two-wave photon Doppler velocimetry measurements in direct impact Hopkinson pressure bar experiments
EPJ Web of Conferences, 2015 Direct impact Hopkinson pressure bar systems offer many potential advantages over split Hopkinson pressure bars, including access to higher strain rates, higher strains for equivalent striker velocity and system length, lower dispersion and faster ...
