An introduction to computational mechanics, this textbook will enable readers to obtain numerical results to difficult problems that cannot be solved by simple computational formulae. Emphasis is placed on the numerical techniques and how they form a basis for algorithms. Numerous worked examples in structural mechanics, heat transfer, fluid flow, and biomechanics are given with the codes to illustrate how the methods are applied. Chapters complete with homework problems, proceed clearly from basic computational tools to advanced computational procedures for applications. A concluding section addresses advanced applications in such areas as finite volume methods.
