Geotechnical modelling guide: material models, parameter ranges, parameter estimation
report
This document contains a brief guide on geotechnical modelling. The focus is on Finite Element modelling (FEM), with some references given to literature that is known to give reasonable analytical results for a few applications (e.g. soil springs derivation). This document is targeted to engineers familiar with FEM but perhaps less familiar with constitutive models for soils or the estimation of soil parameters. The focus is on the material models that are more often used in TNO (elastodynamic, elasto-plastic with memory and the influence of pore pressures) rather than the more advanced models (cyclic behaviour, liquefaction, creep) which could be added in a subsequent study. This limitation allows use of well accepted soil material models and literature for parameter determination. In addition, most FEM packages are able to model these soil behaviours.
