Texture Evolution of AZ31 Magnesium Alloy Sheet at High Strain Rates [PDF]
In the current contribution the mechanical behaviour at high strain rates of AZ31 magnesium alloy sheet is studied. Uniaxial deformation properties were studied by means of tensile split Hopkinson pressure bar (SHPB) at different temperatures.

A dynamic calibration method of free-field pressure sensor based on Hopkinson bar
This paper presents a dynamic calibration method for the dynamic sensitivity coefficient of a free-field pressure sensor working in liquid. In this method, an oil-filled auxiliary tool has been designed and the free-field pressure sensor sealed in the ...

Calibration of a Hopkinson Bar with a Transfer Standard
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.

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]
This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.

Adaptive Twisting Metamaterials
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.
