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.

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

The split Hopkinson bar bulge setup: a novel dynamic biaxial test method [PDF]
EPJ Web of Conferences, 2021 In sheet metal forming, very often, large plastic deformations are imposed to a thin plate. An accurate description of the material’s elastoplastic response is therefore of paramount importance to perform finite element (FE) simulations of an actual ...
