In the last three decades, studies on constitutive models and numerical analysis methods have been well developed. Numerical methods now play a vital role in Geotechnical Engineering and especially in Computational Geotechnics. Detailing the use of constitutive modelling of multi-phase geomaterials and numerical methods , this book will show you how to predict the behaviour of geomaterials.Along with detailed coverage of viscoplasticity, large deformations and multi-phase analysis, it also includes: Recent advances in this area; constitutive modelling of soil for rate-dependent behaviour; applications for multi-phase theory and analysis; water-soil coupling and strain localization. A valuable reference for masters students studying computational geomechanics and for professionals seeking to apply it in practice.
