An outstanding book that provides complete coverage and reflects the latest developments in the field of materials science. The fifth edition maintains its extensive coverage of mechanical properties and failure and offers a new discussion of how the stress state within the body is a function of the orientation of the plane upon which the stresses are taken to act. The accompanying software is updated to include Material Properties and Cost Databases, also found in Appendix B and C of the book. An expanded feature in the software is an equation solver, E-Z Solve, which will help facilitate the solution of mathematically complex problems.
