Tracking Deformation History in Split Hopkinson Pressure Bar Testing
Materials Today: Proceedings, 2016The stress vs. strain curve of materials is affected the rate of imposed straining. Among the methods for dynamic testing the technique known as ‘split Hopkinson pressure bar’ (SHPB) has evolved into the most widely used one to exert high-speed straining. The theory behind it comprises simple equations to compute stress and strain.

A versatile split Hopkinson pressure bar using electromagnetic loading
International Journal of Impact Engineering, 2018Abstract This paper presents a novel electromagnetic split Hopkinson pressure bar (ESHPB), which employs the electromagnetic energy conversion technique of LC circuit to generate directly the incident stress pulse. Such a versatile technique can generate easily compressive as well as tensile incident pulses.

Examination of Validity for Viscoelastic Split Hopkinson Pressure Bar Method
The examination of the accuracy for a split Hopkinson pressure bar method with viscoelastic input and output bars (viscoelastic SHPB method), which is one of the methods of evaluating the dynamic properties for viscoelstic materials, is executed. The key-point for accurately determining the dynamic properties of low impedance materials lies in how to ...T. Tamaogi, Y. Sogabe
