For the last three decades, numerical methods have found a wide range of applications in geomechanics. Of all the numerical methods, the finite element method (FEM) has the maximum applications in geomechanics. This book offers an insight into applications of FEM in designing, analyzing and optimizing structures or excavations made in the rock mass. A fine blend of finite element methodology and principles of rock mechanics, the text emphasizes the basics of stress-strain analysis, isoparametric finite element method, rock mass yielding/failure behaviour and its formulation in FEM procedure, and joint behaviour (as equivalent material and discrete system).
