Abstract

Triaxial Hopkinson techniques can be used to simultaneously subject a sample to axial and lateral compressions. The lateral compression may be applied through a pneumatic pressure vessel or dynamically using a special Hopkinson technique. This article reviews these two techniques in detail. It illustrates a 75-mm Hopkinson system, particularly designed to test large samples of concrete, rock, polymeric composites, and other materials with relatively coarse microstructures. The article also provides information on the pneumatic pressure vessel for a 75-mm Hopkinson bar test system and the dynamic triaxial load cell on a 19-mm Hopkinson bar.
