Abstract
Geotechnical investigation of a project is an important aspect to ensure and improve the functioning of a structure. One of the most commonly used test for geotechnical investigation is cone penetration test which is used in field to determine soil profile and soil properties. This test involves finite scale deformation of soil which is not possible to simulate in a numerical model using the conventional Lagrangian approach. Present work deals with the numerical modeling of field coneion test using coupled Eulerian Lagrangian (CEL) approach in the finite element software Abaqus. Herein the soil is modeled as an Eulerian part to incorporate the finite scale deformation coupled with the cone modeled as a Lagrangian rigid body. The Mohr Coulomb plasticity criterion is used to characterize the behavior of soil in this study. Analysis for cone penetration test is carried out to establish a relationship between mean effective stress and cone bearing pressure for different relative densities of sand. Finally the use of CEL analysis to model finite scale deformation in soil is addressed with its capability to simulate real life geotechnical problems.
