Simplified Equations For Shear-Modulus Degradation and Damping of Gravels by Sébastien PAILLY is a document available to read on EtoBox.
This document presents simplified equations to define the degradation of shear modulus (G) and damping ratio with increasing shear strain for gravels. The G/Gmax versus shear strain equations are based on laboratory tests of 18 gravel investigations and rely on two parameters related to confining pressure and uniformity. Increasing confining pressure leads to a more linear G/Gmax curve, while higher uniformity yields a more nonlinear curve. Estimated standard deviations are provided. The damping ratio equat
