The GDS Electromechanical Dynamic Cyclic Simple Shear Device (EMDCSS) is the premier device for simple shear testing. It is capable of carrying out dynamic cyclic tests ranging from small strain (0.005% shear strain amplitude) to large strain (10% shear strain amplitude), as well as a large range of extremely accurate quasi-static testing. This is the ultimate choice for a no-compromise simple shear machine with the greatest range of testing capabilities. This is the number 1 choice for advanced commercial testing or academic research.
