Behavior of high-density polyethylene at high strain rates
Applied and Computational Mechanics, 2021 The Hopkinson split pressure bar (HSPB) was used for the testing of three polymers at strain rates between 10^2 to 10^3 1/s. Higher strain rates were achieved using the direct Hopkinson test.

Round-Robin test of split Hopkinson pressure bar
International Journal of Impact Engineering, 2019 Abstract A Round-Robin test using split Hopkinson pressure bars (SHPBs) has been conducted by four universities: Swinburne University of Technology (SUT), Australia; University of Sao Paulo (USP), Brazil; University of Cape Town (UCT), South Africa; and Nanyang Technological University (NTU), Singapore. Each university had different sets of SHPBs and

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

Numerical Modeling of a Split Hopkinson Pressure Bar Test
European Journal of Engineering and Technology Research, 2021 In this work, a one-dimensional simplified model was developed to predict stress, strain, and strain-rate in high strain rates Hopkinson pressure bar experiments, namely, between 500-5000/s. To this goal, a one-dimensional model for Hokinson bar tests was developed based on analyses of wave propagation in bars and assuming the specimen is under ...
