Abstract

The concept of a three stress invariants dependent cap model is considered in this work to study the behavior of a rigid continuous footing resting on the surface of dune sand. Laboratory tests are conducted to evaluate the model parameters. The model is then implemented in a finite element code to study the behavior of the footing. The numerical work is based on an incremental iterative procedure using the tangential stiffness method. Two different plane-strain approximations are utilized to solve this problem. The first one is obtained using an elastoplastic matrix, while the second is based on an elastic approximation. The model's extreme versatility and accuracy are verified by comparing its prediction with the observed behavior of an experimental model of a rigid footing. A comparison of the load-displacement curves for the model strip footing by using the three-invariant cap model and the experimental observation shows that the two predictions are very similar.
