If you have a question about this talk, please contact Zelda Stuck.

Finite element modelling is currently used fairly routinely in geotechnical design, often based on relatively simple soil mechanics learnt at undergraduate level, or just beyond. The talk will recount a situation in which basic concepts interacted in an unexpected way, leading to misconceptions about commercially available FE programs. A key aspect, routinely overlooked, proved to be the dilational behaviour of the ground, and of the FE programs.
