Two series of experiments are performed to investigate the dynamic response of various essential components of a class of sandwich structures, under high-rate inertial loads. One consists of dynamic inertia tests and the other involves dynamic impact tests. A split Hopkinson bar apparatus is modified and used for these experiments. First, the energy-absorbing characteristics of the plate materi...

Local loading conditions associated with shear banding formation in laboratory -@ten alloy specimens are examined. The specimens consist of compression specimens of large length to diameter ratio made of 91W-6Ni-3Co swaged tungsten alloys tested with the Hopkinson pressure bar and symmetric Taylor techniques. Experimental and numerical results provide insights on the effect of the hydrostatic p...

Abstract The coal mining process is affected by various water sources such as groundwater and seam injection. Understanding the dynamic mechanical parameters of water-immersed helpful for coalmine safe production. impact compression tests were performed on with different moisture contents using ϕ 50 mm Split Hopkinson Pressure Bar (SHPB) experimental system, characteristics energy loss laws com...
