Calibration of a Hopkinson Bar with a Transfer Standard [PDF]
Shock and Vibration, 1993 A program requirement for field test temperatures that are beyond the test accelerometer operational limits of −30° F and +150° F required the calibration of accelerometers at high shock levels and at the temperature extremes of −50° F and +160° F. The purposes of these calibrations were to insure that the accelerometers operated at the field test ...

Correction Procedure of Wave Signals for a Viscoelastic Split Hopkinson Pressure Bar [PDF]
Problemy Mechatroniki, 2016 A polymeric split Hopkinson pressure bar technique (SHPB) is preferred for testing materials with low mechanical impedance. However, the use of polymeric bars requires additional analysis for data reduction, temperature complications and additional ...

Design considerations for joining of tubular members subjected to impact loading
Journal of Advanced Joining Processes, 2021 This study explores the effect of impact loading in structural bar and tube welded and threaded joints. Specifically, this work concentrates on stress wave propagation and mechanical impedance to show the effect of geometric parameters on stress ...

A comparative study on the restrictions of dynamic test methods
EPJ Web of Conferences, 2015 Dynamic behavior of materials is investigated using different devices. Each of the devices has some restrictions. For instance, the stress-strain curve of the materials can be captured at high strain rates only with Hopkinson bar. However, by using a new

High strain rate response of UHP(FR)C in compression
EPJ Web of Conferences, 2015 The objective of this study was to investigate the compression behaviour of the UHPFRC and its matrix (UHPC) under high strain rate. Two experimental set-ups were used for compression testing: a traditional Split Hopkinson Pressure Bars and a compression

High strain rate tensile testing of sheet materials using three Hopkinson pressure bars
EPJ Web of Conferences, 2012 In an attempt to circumvent the inherent problems associated with Split Hopkinson Tensile Bar (SHTB) systems, a new experimental technique is proposed for the high strain rate tensile testing of sheet specimens in Split Hopkinson Pressure Bar (SHPB ...
