Abstract Magnetorheological (MR) fluids are classified as smart materials whose viscoplastic characteristics change under the magnetic field. They widely applied for dynamic energy dissipation due to their rapid thickening external In this work, core–shell suspension of superparamagnetic iron oxide-based nanoparticles was synthesized and dispersed in silicone oil. Much effort has been made prep...

A technique is developed for measuring the flow stress of metals over a broad range of strains, strain rates, and temperatures, in uniaxial compression. It utilizes a recent, enhanced version of the classical (Kolsky) compression split Hopkinson bar [l], in which a sample is subjected to a single stress pulse of a predefined profile, and then recovered without being subjected to any other addit...

Abstract Abstract.To explore the mechanical behavior of carbon fiber reinforced plastics (CFRP) under high launch overload, this study presents a laboratory loading technological method for chamber-pressure curve simulation overload using Φ100 mm-diameter split-Hopkinson pressure bar (SHPB) device. On basis, experiments are carried out to dynamic compression properties and failure modes CFRP cy...

The mechanical response and deformation mechanisms of TB17 titanium alloy were studied at room temperature by the split-Hopkinson pressure bar test. ultimate compression strength increases from 1050 MPa to 1400 MPa, as strain rate 2000 s?1 2800 s?1. adiabatic shear failure occurred When was s?1, only {10 9 3}<331>? type II high index twins, a small number ?” martensite, interfacial ? phas...
