This text is intended to address the applications of the finite element methods (FEMs) in the area of rock mechanics. The text emphasizes the fundamental concepts of stress-strain analysis, isoparametric finite element method, concepts and numerical implementation of rock mass yielding/failure behaviour, joint behaviour as equivalent material and as discrete system, and interaction between rock bolts and rock mass. A tunnel problem is solved to emphasize the application of the finite element method in geomechanics. The book is intended for senior undergraduate and postgraduate students of Mining, Civil and Geotechnical Engineering. It would also be useful to the practising engineers and researchers who wish to acquaint themselves with the state-of-the-art techniques of finite element methods.
