Abstract
Micromechanical and anisotropic behavior of soils is analyzed using the plastic spin and anisotropic modified Cam clay model (AMCCM) in an updated Lagrangian reference frame. The micromechanical behavior of soils is especially important in large strain problems. The anisotropic behavior inherently exists in soils. This study uses AMCCM with the plastic spin to evaluate the pore pressure response in cone penetration tests. This test is a typical example for large strain problems. The analytical results indicate that the predicted pore pressure is closer to the measured one when the plastic spin is incorporated in AMCCM. It also shows that the micromechanical behavior is paramount in the vicinity of the cone tip where large strains and rotations occur.
