A Constitutive Model for Saturated Gravelly Sand Based on Higher-Order Dilatancy Equation
Effect of material parameters s and t on the high-order dilatancy equation. (a): s-high-order dilatancy equation (Dr = 0.35, σ3 = 50 kPa, M = 1.37, and t = 0.75). (b) t-high-order dilatancy equation (Dr = 0.55, σ3 = 50 kPa, M = 1.4, and s = 2).
