Time-Dependent Behavior of Geomaterials book cover

Time-Dependent Behavior of Geomaterials

Experimental Observations and Modeling Approaches

As the geotechnical engineering profession increasingly draws upon analytical modeling implemented in numerical modeling, the demand for more advanced, and thus more accurate, depictions of soil behavior will be needed. Time-Dependent Behavior of Geomaterials: Experimental Observations and Modeling Approaches provides civil engineers and researchers working in this area with a variety of geomechanics modeling tools ranging from field testing interpretation to modeling of geotechnical design responses to various loading conditions.

With this book in hand, both researchers and practitioners receive a more sophisticated treatment of complex behavior topics including: interpretation and modelling of test results from short-term field instrumentation as they apply to long-term phenomenon (e.g., landslides); validation of modelling for interpreting and extrapolating laboratory test results for field applications; and understanding the complexities of measurements and modelling of highly complex, multiphase, anisotropic geomaterials
