Title Generation of shape functions for rectangular plate elements.
Output type: Journal article
Journal title: Communications in numerical methods in engineering.
Month/year of publication: August 2004
Pagination: 655-663
Volume: 20
ISSN: 1069-8299
URL: Original article on web ?
DOI: 10.1002/cnm.703 ?
Other relevant details: Development of automated system of producing shape functions, necessary for finite element analysis, the most widely used computational tool in solid mechanics. Proposed technique automates shape function generation for a large range of plate elements. This work carried out entirely by Augarde alone.

Title Prediction of undrained sinkhole collapse.
Output type: Journal article
Journal title: Journal of geotechnical and geoenvironmental engineering.
Month/year of publication: March 2003
Pagination: 197-205
Volume: 129
ISSN: 1090-0241
URL: Original article on web ?
DOI: 10.1061/(ASCE)1090-0241(2003)129:3(197) ?
Co-authors: Lyamin, A. V, Sloan, S. W.
Other relevant details: Development of new analytical method for predicting likelihood of sudden ground failure and sinkhole formation in soft ground. Augarde carried out all analysis and wrote the paper while on research leave at the University of Newcastle, Australia, working there with the co-authors. This paper contains the first rigorous analytical technique for sinkhole formation prediction due to subsurface cavity collapse in soft ground.

Title A hybrid meshless local Petrov Galerkin method for unbounded domains.
Output type: Journal article
Journal title: Computer Methods in Applied Mechanics and Engineering
Month/year of publication: January 2007
Pagination: 843-852
Volume: 196
ISSN: 0045-7825
URL: Original article on web ?
DOI: 10.1016/j.cma.2006.06.011 ?
Co-authors: Deeks, A.J.
Other relevant details: The first description of a hybrid numerical method for solid mechanics coupling meshless and scaled boundary techniques. Augarde took equal role with the co-author (Prof. Deeks, UWA, Australia) in development of technique and paper preparation. Work continues in this area; Augarde won a £338K grant from EPSRC to continue development of the method in 2006, for industrial applications in geotechnics. The method has a number of major advantages over conventional methods such as finite elements, being able to model infinite boundaries and non-linear behaviour in the near-field. Many potential applications also exist outside civil and mechanical engineering.

Title Element-based preconditioners for elasto-plastic problems in geotechnical engineering
Output type: Journal article
Journal title: International Journal for Numerical Methods in Engineering
Month/year of publication: August 2007
Pagination: 757-779
Volume: 71
ISSN: 0029-5981
URL: Original article on web ?
DOI: 10.1002/nme.1947 ?
Co-authors: Ramage, A., Staudacher, J.
Other relevant details: Development of methods to speed up finite element calculations for the large linear systems arising in geotechnics. First study to investigate effect of plasticity on choice of iterative solution techniques, particularly preconditioning. Augarde has worked closely with first co-author (in Maths at Strathclyde) since 2002 in this area and has held two EPSRC grants jointly with her. Industrial developer of geotechnical FE software OASYS Ltd (part of Arup) plans to implement these ideas (Contact carol.matthews@arup.com). OASYS have supported Augarde and Ramage as partner in an EPSRC responsive mode application for further research.
