An a posteriori error estimator for plane-strain geotechnical analyses
journal contribution
posted on 2009-08-18, 15:43 authored by Ashraf El-HamalawiAshraf El-Hamalawi, M.D. BoltonIn this paper, an a posteriori error estimator suitable for use in geotechnical engineering has been developed. This error criterion is based on the superconvergent patch recovery method with equilibrium and boundary conditions method, taking into account Biot's coupled consolidation theory. After testing on several problems, the introduction of pore pressures and other parameters into the error estimator was found to improve results significantly, providing a convergence rate of approximately two orders higher than the global rate.
