'… because Dym writes with sufficient clarity to allow readers with a classic structural analysis background to develop a foundation on which to build computerized versions of stiffness and flexibility, his book will be an excellent foundation for understanding modern computational methods of stress analysis used in aeronautical, civil, and mechanical engineering. Readers needing background in fundamental energy methods will find this an excellent 'kick-starter' for preparing finite element techniques. A very positive recommendation for libraries collecting books on structural analysis.' W. C. Schnobrich, Choice
