Elasticity: Constitutive Modelling in Geomechanics

This lecture by the instructor covers the theory of constitutive equations in geomechanics, focusing on the stress-strain behavior of geomaterials and the development of constitutive laws. It discusses the steps involved in developing constitutive laws, the significance of parameters, and the comparison between predictions and observations. The lecture also explores the application of elastic models in analytical and numerical methods through case studies of gravity-arch and buttress dam stability, emphasizing the importance of appropriate constitutive material models and boundary value analysis.
