Test Method Title
Standard Test Methods for the Determination of the Modulus and Damping Properties of Soils Using the Cyclic Triaxial Apparatus
Reference Number
ASTM D3999
Material
Soil
Test Property
Young's Modulus and damping ratio, axial strain
Description of Test
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.
Number of Test Specimens
1
Test Specimen Size
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.
