Publisher: CL Engineering, 1997

Based on the Second Edition of Daryl Logans best-selling book, A First Course in the Finite Element Method, this new book replaces the Second Editions generic computer-based examples and problems with new ones based on the use of Algor, a popular FEM software package used by professionals and site-licensed by many leading engineering schools. Logan gears his text to undergraduate-level students who will use FEM and Algor to study practical physical problems of structural stress analysis and heat transfer.
