The aim of this book is to provide Bachelor (BSc) and Master (MSc) of Science students, as well as professional mechanical and civil engineers, with a complete and unified coverage of finite element analysis and to demonstrate how FEM can be programmed Throughout the text, readers are shown step-bystep detailed FE analyses of integrated engineering problems. For this purpose, analytic mathematics is used for the development of stiffness matrices for widely used elements in mechanical and structural
engineering practice. To help readers to understand how the boundary conditions can be taken into account in the procedure of the FE modeling, a special type of structural matrix equation incorporating both global stiffness matrix and submatrices containing the boundary conditions in a unified form is proposed.
After completing FEM courses, new engineers would be expected to have adequate knowledge to use a commercial FEM program in their first job. Among the targets of the book is to assist readers to understand the architecture of FEM software, as well as its limitations. Since computer coding to solve FEM problems is the required background for subsequent learning how to use commercial package software intelligently and critically, effort has been made to teach readers how to develop their own programs in order to understand the fundamental abilities of commercial packages. Therefore, the aims of the book are:
(1) to provide the tools to help students and engineers to be software developers, and (2) to provide “how-to” knowledge in running a commercial FEM program. To achieve the first aim, the book uses a contemporary computer-aided learning platform, called CALFEM, which adopts the facilities of the well-known computational matrix laboratory MATLAB. For common types of structures (e.g., trusses, beams, frames, hybrid structures, structural dynamic problems, etc.), the book provides the logical steps for developing an FEM computer algorithm. In the offered examples, the analysis of the required software commands, the computer code, and the numerical/graphic results are also exhibited. To achieve the second aim, a self-learning on “how-to” run the widely used commercial FEM program ANSYS is provided. To this end, most of the examples treated with the CALFEM/MATLAB platform are used for step-bystep ANSYS learning. Therefore, the ANSYS windows for data entry are provided and the required commands are described through a combination of text and graphics.
This book introduces FE methodology with simple concepts (e.g., the method of direct equilibrium) and progresses to more complicated principles (such as variational methods), allowing a smooth transition of the reader to deeper knowledge of the method.
