Description
Summary:A numerical implementation of the "bounding surface plasticity" model for cohesive soils is described. An adaptive multistep integration procedure is used in conjunction with local iteration and radial return. Emphasis is placed on the development of a robust algorithm. The incorporation of the material model into finite element codes for stress-consolidation problems in geotechnical engineering is described. Example analyses are given for one element problem, an idealized footing problem and two centrifugal simulations of field problems.
