  1、The system would directly proceed digital servo control on all three principal stresses/strains to simulate in-situ large stress/strain path testing, including plane strain, Ko and small shear strain. The other testing supplied include dynamic shear strength and deformation, shear modulus and damping ratio, and other user-defined programs;
  2、With dynamic-static loading function.
  3、With multi-direction vibration loading function of axial direction & confining pressure or horizontal direction.
  4、Freely converting of stress/strain control.
  5、The P/q path could freely control the stress path during testing.
  6、They are common compression system between static-dynamic pressure.
  Model RSTD-10
