On preconditioning strategies for geotechnics
Iterative solvers are of increasing interest in geomechanics with the move towards 3D finite element modelling. Potentially, these methods can lead to reduced computational complexity as, unlike direct methods, they do not require the full system matrix to be assembled. In general, however, iterative solvers have not been widely adopted in geomechanics due to problems with convergence. This pap...
متن کاملGeneral report TC202: transport geotechnics
Today's needs of urban transportation including roads, railways, airports and harbours demand significant resources for infrastructure development in view of rapid and efficient public and commercial (freight) services. In most cases, authorities have had difficulties in meeting these service demands due to the rapidly growing public, industrial, mining and agricultural sectors in many parts of...
متن کاملApplication of Digital Photogrammetry in Geotechnics
Acquiring geometric data, such as coordinates, displacements or deformations, has always been a way to verify mathematical modelling in civil engineering. The introduction of finite elements methods further reinforced this trend. This paper reports on two applications of photogrammetry to soil and rock mechanics in order to provide an accurate and dense description of the deformation fields of ...
متن کاملDevelopments in Microcomputer Network Analysis Tools for Transportation Planning
M icrocomputers have been in regular use by transportation professionals since about 1980. As a result, there is a base of experience for assessing the available software, as well as for suggesting directions for software development. Although the focus of this article is on microcomputer software, which is taking an increasingly larger share of the market, many of the comments apply equally we...
متن کاملLower Bound Shakedown Analysis in Geotechnics
The paper describes some recent developments in the application of lower bound shakedown analysis to geotechnical problems. The theoretical basis of shakedown analysis is briefly reviewed along with the necessary finite element and optimization procedures. In terms of applications, the primary focus is on pavement design which is discussed in some detail.
