Fracture Analysis of Ultrahigh-Strength Steel Based on Split Hopkinson Pressure Bar Test
Impact loading is an important cause of fracture failure of ultrahigh-strength steel parts during service. Revealing the fracture mechanism of ultrahigh-strength steel under impact loading has important reference significance for the material preparation,

On the use of a viscoelastic split hopkinson pressure bar
To test weak materials such as foams at high strain rates, the use of a Split Hopkinson Pressure Bar (SHPB) setup made of low impedance bars, which are mostly viscoelastic, is indispensable. In this paper a detailed study of the technical problems of such a viscoelastic setup related to the measurement and to the loading conditions is offered.

Round-Robin test of split Hopkinson pressure bar
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

Numerical Modeling of a Split Hopkinson Pressure Bar Test
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 ...

Split‐Hopkinson‐Pressure‐Bar simulations using MPM [PDF]
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

Polypropylene foam behaviour under dynamic loadings: Strain rate, density and microstructure effects [PDF]
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.
