Finite Element Method popularly known as FEM has undergone a major paradigm shift from a detailed mathematical background to write tailor made computer programs, to an understanding of the subject for better utilisation of available software such as ANSYS, NISA, ADINA, PAFEC, NASTRAN etc. The author with his rich experience, has made an effort in this direction and prepared a textbook on FEM ideally suited for engineering students and design engineers. Special Features • Comprehensive study material including all relevant topics – approximate methods, matrix operations and theory of elasticity
• Example problems & case studies for better understanding of the concepts
• Includes properties of ductile and brittle materials, for design checks • Solved problems & objective questions – for students
• Examples with a commercial software (ANSYS), common data mistakes and validation of results for code compliance – for practicing design engineers
• Brief coverage of fracture mechanics, contact and gap elements & CFD.
