Young's Modulus and damping ratio, axial strain
The cyclic triaxial test consists of imposing either a cyclic axial deviator stress of fixed magnitude (load control) or cyclic axial deformation (stroke control) on a cylindrical soil specimen enclosed in a triaxial pressure cell. The resulting axial strain and axial stress are measured and used to calculate either stress-dependent or stroke-dependent modulus and damping.
1.4 in diameter minimum with a height-to-diameter ratio of between 2 and 2.5. The largest particle shall be smaller than 1/6 the specimen diameter.
