The Hopkinson split pressure bar (HSPB) was used for the testing of three polymers at strain rates between 102 to 103 s-1. Higher were achieved using direct test. Experimental data evaluated in time as well frequency domain. A more detailed analysis domain showed that description tested can be described framework linear viscoelasticity. use test occurrence a permanent strain.

The possibility of increasing the static and dynamic strength aluminum-magnesium alloy AMg4.5 is shown by using methods severe plastic deformation, a combination annealing additional deformation ultrafine grained alloy. properties material are evaluated structural-temporal approach to analysis experimental data on tension small samples obtained split-Hopkinson pressure bar. Keywords: strength, ...

The dynamic characteristics of the Charpy test have been studied by means OF a Hopkinson bar apparatus and photoelasticity. It is Found that this technique permits a clear evaluation of the test results, and is preferable to the standard instrumented pendulum test.

The main aim of this work is to analyse the quasi-static and dynamic response deformation behaviour polymeric auxetic structures manufactured with an SLA (stereolitography) additive manufacturing technique. To end, different experimental tests were performed using a universal servo-hydraulic instron machine Split Hopkinson Pressure Bar (SHPB). study focuses on understanding mechanical metamater...
