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 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)
