Overview

Numerical modeling study demonstrates accurate prediction of large deformations in granular soils, highlighting explicit micromechanical analysis as a robust tool for geotechnical engineering.

Key Points

  • Integrate a micromechanics-based constitutive model into an explicit finite element framework to reliably simulate large deformations and strain localization in granular soils without numerical convergence issues.
  • Implemented a micromechanical constitutive model with physically meaningful parameters into an explicit finite element code to replace standard implicit solvers.
  • Validated the numerical framework using benchmark biaxial tests and footing settlement analyses.
  • Simulated complex large-deformation geotechnical problems, including retaining wall displacements, an axially loaded closed-ended pile, and a novel bucket foundation.
  • Retaining wall simulations successfully captured shear band patterns that agreed with experimental observations and Discrete Element Method simulations under active and passive modes.
  • Computed axial load capacity for the closed-ended pile demonstrated close alignment with centrifuge test data.
  • Analyses of a novel bucket foundation confirmed the robustness of the explicit framework in handling intense strain localization without solver divergence.
