Modeling cyclic liquefaction in sand : from system-scale analysis to constitutive modeling with fabric anisotropy and memory effects

Key Points

• The aim is to develop a comprehensive model for cyclic liquefaction in sand, integrating fabric anisotropy and memory effects.
• Conduct system-scale analysis to understand cyclic liquefaction dynamics.
• Develop constitutive models that incorporate fabric anisotropy and memory effects.
• Evaluate model performance against experimental data.
• The model shows improved prediction accuracy for liquefaction behavior under cyclic loading conditions.
• Incorporating fabric anisotropy enhances the understanding of sand's response to seismic forces.
• Memory effects contribute to the long-term stability of the sand structure against liquefaction.
