Autodesk Simulation Mechanical, a product of Autodesk Inc., is a world’s leading, widely distributed, and popular commercial CAE package. Autodesk Simulation Mechanical is being used by designers across a broad spectrum of industries such as aerospace, automotive, manufacturing, nuclear, electronics, biomedical, and many more. It provides simulation solutions that enable designers to simulate design performance directly on the desktop. In this way, it dispenses fast, efficient, and cost-effective product development from design concept stage to performance validation stage of the product development cycle. Autodesk Simulation Mechanical package streamlines the product development process by resolving issues related to structural deformation, heat transfer, fluid flow, electromagnetic effects, a combination of these phenomena, and so on. Autodesk Simulation Mechanical 2014 for Designers textbook has been written with an intention to assist engineers, engineering students, and practicing designers new to the field of FEM and CAE. The textbook covers of FEA concepts, modeling, and analysis of engineering problems using Autodesk Simulation Mechanical. In addition, enough theoretical background is offered to allow individuals to use Autodesk Simulation Mechanical as simulation package. This textbook covers Static Stress Analysis, Natural Frequency (Modal) Analysis, Frequency Response Analysis, Transient Stress Analysis, and Non-linear Analysis.
