WebThe GDS Electromechanical Dynamic Cyclic Simple Shear Device (EMDCSS) is for simple shear testing, which can be upgraded to direct shear. It is capable of carrying out dynamic cyclic tests from small strain (0.005% shear strain amplitude) to large strain (10% shear strain amplitude), as well as extremely accurate quasi-static testing. WebJan 3, 2024 · Dynamic shear tests. Dynamic shear tests (strain rate >2000 \(s^{-1}\)) are performed at room temperature by means of the split-Hopkinson pressure bar (SHPB) technique . The flat hat-shaped specimen used for dynamic shear testing is located between the incident and transmitter bars.
