Finite Element Analysis and Constitutive Modelling in Geomechanics

The Finite Element Analysis and Constitutive Modelling in Geomechanics course provides an advanced understanding of numerical modeling techniques used to analyze the mechanical behavior of soils and rocks. The course focuses on applying the finite element method (FEM) to solve complex geotechnical problems involving stress–strain behavior, deformation, and failure under various loading and boundary conditions.

The course begins with the fundamentals of finite element formulation, including discretization, shape functions, and solution procedures. It then introduces constitutive modeling of geomaterials, explaining how different stress–strain relationships represent soil and rock behavior under elastic, elasto-plastic, and time-dependent conditions. Emphasis is placed on understanding widely used constitutive models and their implementation in numerical analysis. Practical applications such as foundation analysis, slope stability, tunneling, excavation, and soil–structure interaction are integrated throughout the course.

By the end of the course, learners develop the ability to select appropriate constitutive models, build numerical models, interpret results, and apply FEM tools to real-world geotechnical engineering problems.
