A Split Hopkinson Bar Technique to Determine Compressive Stress-Strain Data for Rock Materials [PDF]

, 2000
We present a split Hopkinson pressure bar technique to obtain compressive stress-strain data for rock materials. This technique modifies the conventional split Hopkinson bar apparatus by placing a thin copper disk on the impact surface of the incident ...

A testing technique to investigate the tensile behavior of propellant representative material

EPJ Web of Conferences, 2018
Propellants are energetic materials abundantly used to generate the propulsion of rockets, projectiles, or other objects. A wide range of stress-state and strain-rate has to be considered in view of predicting the mechanical behaviour of this material ...
