Prerequisite
  

Basic Undergraduate Course in Soil Mechanics/Geotechnical Engineering

Graduate Standing

 
Course Objectives  

This course is an introduction to modeling and computing in Geomechanics. With reference to several practical problems, different phases (idealization of physical problem, formulation of mathematical models, and development of the numerical solution and their visualization) of modeling and computing will be illustrated. Analytical, semi-analytical, and numerical methods (finite difference and finite element) will be developed and implemented in computer programs. The areas of application will include: seepage analysis, analysis of consolidation; stress analysis, flow and deformation analysis, contaminant migration, deflection of laterally loaded piles and wave propagation.
