Three-Dimensional Finite Element Analysis of Footing Resting on Sand
(2003) Third International Conference on Deformation Characteristics of Geomaterials 1. p.939-946- Abstract
- Numerical analysis, such as the finite element method
is the most used computational procedure for nonlinear deformation
and strength analysis of structures. In order to obtain meaningful
results the material behaviour must be described and simulated
accurately. Another important element in order to perform the
simulation is a robust and accurate numerical integration
algorithm. The present paper is focused on three-dimensional
numerical simulation of footing resting on sand. The complex nature
of soil behaviour, depending on void ratio and stress state is
highly non-linear and it is modeled with a non-associated
plasticity model developed by Krenk... (More) - Numerical analysis, such as the finite element method

numerical simulation of footing resting on sand. The complex nature
of soil behaviour, depending on void ratio and stress state is
highly non-linear and it is modeled with a non-associated
plasticity model developed by Krenk (2000). The model has been
implemented as a user-defined mechanical material behavior in
ABAQUS finite element code using an implicit integration algorithm
with explicit update of the hardening parameter, presented in Ahadi
& Krenk (2003). The implemented subroutine is used to study the
deformation and strength behaviour of sand subjected to load with
flexible footing. Both strip footing under plain strain conditions
and three dimensional square footing are analyzed. The simulations
are performed using large strains in order to account for
geometrical nonlinearities. The deformation behaviour, vertical
stress distribution and the settlement beneath the footing from the
strip and the square footings are compared. (Less)
