WebOct 10, 2024 · The split Hopkinson pressure bar method (SHPB) is currently the most widely used material testing method for a high strain rate. Although many articles on the methodological aspects of SHPB testing have been published, some methodological issues have not yet been fully analysed. WebJun 28, 2024 · The mechanical response of IM7-8552 carbon epoxy was investigated for transverse tension and transverse tension/in-plane shear loadings at static and dynamic strain rates using transverse tension and off-axis tension specimens. The dynamic tests were carried out on a split-Hopkinson tension bar at axial strain rates from 113 to 300 …

Dispersion Investigation in the Split Hopkinson Pressure Bar

WebThis paper presents the design of a modiﬁed split Hopkinson pressure bar (SHPB) where partial lateral con-ﬁnement of the specimen is provided by the inertia of a ﬂuid annulus contained in a long steel reservoir. In contrast to unconﬁned testing, or a constant cell pressure applied before axial loading, lateral restraint is per- WebDec 27, 2012 · The authors systematically describe the general principles of Kolsky bars, or split Hopkinson bars, which are widely used for obtaining dynamic material properties. … cannot find module semver npm
