Offers the MATLAB[registered] and C programming processes in applications of the Trefftz FEM to potential and elastic problems. This book presents MATLAB and C subroutines for inputting data and outputting results, Gaussian integration, generating shape functions, assembling an elemental stiffness matrix, and introducing boundary conditions. "The book begins with an introduction to the hybrid-Tretz (HT) FEM that covers basic concepts and general element formulations of the method. It then concentrates on both the essentials and subroutines of MATLAB and C programming. The next few chapters present applications of T-elements to potential problems and linear plane elasticity, discuss how to solve body force in elasticity through radial basis functions, and examine how special purpose functions can be constructed. The final chapter explores advanced topics, such as the construction of Tretz p-elements, dimensionless transformation, and an alternative formulation to HT FEM. Unifying the computer programming aspects of the Tretz FEM, this book will stimulate the development and application of this novel method in many facets of practical engineering."-Zentralblatt MATH
