  • The recorded data by cyclic triaxial testing are discrete and limited, the relationships of data need to be fitted for easy use, however the present expirical equation is not available for testing data. To obtain the value of shear modulus and damping ratio for different shear strain, the piecewise polynomial fitting method is applied to normalized shear modulus and damping ratio versus shear strain based on least-square principle. The value of shear strain is converted to avoid the equation set ill-conditioned due to the great difference in shear strain magnitude. The fitting results is satisfactory by using the piecewise lower polynomial order fitting.
