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

Polypropylene foam behaviour under dynamic loadings: Strain rate, density and microstructure effects [PDF]
, 2009 Expanded polypropylene foams (EPP) can be used to absorb shock energy. The performance of these foams has to be studied as a function of several parameters such as density, microstructure and also the strain rate imposed during dynamic loading.

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 ...
