Lower bound limit analysis using finite elements and linear programming

- S. Sloan
- Mathematics
- 1988

This paper describes a technique for computing lower bound limit loads in soil mechanics under conditions of plane strain. In order to invoke the lower bound theorem of classical plasticity theory, a… Expand

The ultimate pullout capacity of anchors in frictional soils

- R. Merifield, S. Sloan
- Geology
- 1 August 2006

During the last 30 years various researchers have proposed approximate techniques to estimate the uplift capacity of soil anchors. As the majority of past research has been experimentally based, much… Expand

Refined explicit integration of elastoplastic models with automatic error control

Effective explicit algorithms for integrating complex elastoplastic constitutive models, such as those belonging to the Cam clay family, are described. These automatically divide the applied strain… Expand

Upper bound limit analysis using discontinuous velocity fields

- S. Sloan, P. Kleeman
- Mathematics
- 1 November 1995

Abstract A new method for computing rigorous upper bounds under plane strain conditions is described. It is based on a linear three-noded triangular element, which has six unknown nodal velocities… Expand

An algorithm for profile and wavefront reduction of sparse matrices

- S. Sloan
- Mathematics
- 1 February 1986

SUMMARY An algorithm for reducing the profile and wavefront of a sparse matrix is described. The scheme is applicable to any sparse matrix which has a symmetric pattern of zeros and may be used to… Expand

A smooth hyperbolic approximation to the Mohr-Coulomb yield criterion

Abstract The Mohr-Coulomb yield criterion is used widely in elastoplastic geotechnical analysis. There are computational difficulties with this model, however, due to the gradient discontinuities… Expand

Stability of plate anchors in undrained clay

- R. Merifield, S. Sloan, H. Yu
- Engineering
- 1 March 2001

Soil anchors are commonly used as foundation systems for structures requiring uplift resistance, such as transmission towers, or for structures requiring lateral resistance, such as sheet pile walls.… Expand

Two- and three-dimensional bearing capacity of foundations in clay

- R. Salgado, A. Lyamin, S. Sloan, H. Yu
- Geology
- 1 June 2004

Bearing capacity calculations are an important part of the design of foundations. Most of the terms in the bearing capacity equation, as it is used today in practice, are empirical. Shape factors for… Expand
