A unique, hands–on introduction to the Finite Element Method
Fundamental Finite Element Analysis and Applications: with Mathematica® and MATLAB® Computations is an innovative, practical guide to discovering the Finite Element Method (FEM). Providing a helpful balance between theory and application, it presents the FEM as a tool to find approximate solutions of differential equations, making it a useful resource for students from a variety of disciplines.
Using a unique combination of live Mathematica® and MATLAB® implementations, along with problems in both ANSYS® and ABAQUS® formats, this hands–on book reveals the logic behind the equations to facilitate a full understanding of methods and solutions. In nine convenient chapters, Fundamental Finite Element Analysis and Applications: with Mathematica® and MATLAB® Computations covers:Finite Element Method: The Big PictureMathematical Foundation of the Finite Element MethodOne–Dimensional Boundary Value ProblemsTrusses, Beams, and FramesTwo–Dimensional ElementsMapped ElementsAnalysis of Elastic SolidsTransient Problemsp–Formulation
An associated Web site (wiley.com/go/bhatti) includes interactive application files and notebooks for Mathematica®, MATLAB®, ANSYS®, and ABAQUS®, with expanded exercises to use with the book.
Fundamental Finite Element Analysis with Mathematica® and MATLAB® Computations is a clear and accessible learning tool for senior undergraduate and graduate–level students.
