ANSYS APDL is an important and necessary program in various engineering fields. All engineers and professionals need the basic knowledge about this program to improve their skills and practice on how to establish their own model in terms of design and material requirement, process and control tooling, and the use of sophisticated and skillful computer software programs. Therefore, this book is mainly devoted to help graduate students who are not familiar with the designing and constructing model to conduct their experimental projects, especially in the ¿Mechanical Engineering¿ field. It is also useful for postgraduate students during their higher studies to develop their ability to design and build the model for the B.Sc., MSc and PhD work. Moreover, it is beneficial for working engineers in the Research and Development Centers to enhance their scientific capability and gives them the proper procedure to design and construct the relevant model. The reader is assumed to be familiar with the preliminary courses of mechanical drawing research works.
