This thorough reference work discusses various causes of failure with integrated coverage of process metallurgy of steels by forging, casting, welding, and various heat treatment processes. The breadth of coverage and the numerous examples provide an invaluable resource for the designer, engineer, metallurgist, mechanical and materials engineers, quality control technicians, and heat treaters.
Potential failures of heat treated steel are detailed to help identify cause in preventing future occurrence and improving reliability of heat treating process and part performance. With a detailed focus on steel failures, this work can help identify root causes of failure, even if a thermal process is not specifically being considered as cause.
Potential failures are covered with respect to design, material composition, component production, and thermal processing. Beginning with design aspects of component failure, chapters are devoted to several aspects of steel manufacturing including casting, forging or powder metallurgy in addition to heat treating operations.
Topics include production problems such as porosity, flaws, and surface defect that may influence failures occurring during subsequent heat treatment or during use. Many examples of heat treatment failures are provided with special focus on the demands of tool steels and aerospace materials.

Author(s)/Editor(s): Michael R. Hatch | Size: 9.19 MB | Format:PDF | Quality:Original preprint | Publisher: Chapman and Hall/CRC | Year: 2000 | pages: 656 | ISBN: 9781584882053
Transfer function form, zpk, state space, modal, and state space modal forms. For someone learning dynamics for the first time or for engineers who use the tools infrequently, the options available for constructing and representing dynamic mechanical models can be daunting. It is important to find a way to put them all in perspective and have them available for quick reference.
It is also important to have a strong understanding of modal analysis, from which the total response of a system can be constructed. Finally, it helps to know how to take the results of large dynamic finite element models and build small MATLAB® state space models.
Vibration Simulation Using MATLAB and ANSYS answers all those needs. Using a three degree-of-freedom (DOF) system as a unifying theme, it presents all the methods in one book. Each chapter provides the background theory to support its example, and each chapter contains both a closed form solution to the problem-shown in its entirety-and detailed MATLAB code for solving the problem.
Bridging the gap between introductory vibration courses and the techniques used in actual practice, Vibration Simulation Using MATLAB and ANSYS builds the foundation that allows you to simulate your own real-life problems.
Features
Demonstrates how to solve real problems, covering the vibration of systems from single DOF to finite element models with thousands of DOF
Illustrates the differences and similarities between different models by tracking a single example throughout the book
Includes the complete, closed-form solution and the MATLAB code used to solve each problem
Shows explicitly how to take the results of a realistic ANSYS finite element model and develop a small MATLAB state-space model
Provides a solid grounding in how individual modes of vibration combine for overall system response

Summary
The complexity of modern-day problems in mechanical engineering makes relying on pure theory or pure experiment impractical at best and time-consuming and unwieldy at worst. And for a large class of engineering problems writing computer codes from scratch is seldom found in practice. Use of reputable, trustworthy software can save time, effort, and resources while still providing reliable results. Finite Elements Simulations Using ANSYS focuses on the application of this design software in solving practical engineering problems.
The book presents fundamental knowledge of numerical simulation using ANSYS. It covers all disciplines in mechanical engineering: structure, solid mechanics, vibration, heat transfer, and fluid dynamics, with adequate background material to explain the physics behind the computations. The author treats each physical phenomenon independently, enabling readers to single out subjects or related chapters and study them as self-contained units. Because a finite element solution is greatly affected by the quality of the mesh, a separate chapter on mesh generation is included as a simple meshing guide, emphasizing the basics. Each chapter contains a number of pictorially guided problems with appropriate screenshots that provide a step-by-step, easy-to-follow technical demonstration. The book includes end-of-chapter problems, several practical, open-ended case studies, and a number of complete tutorials on using ANSYS to resolve the issues engineers tackle on a regular basis.
Instructors can liberally select appropriate chapters to be covered depending on the objectives of the course. The author first explains multiphysics analyses, such as structure-thermal or fluid-thermal analyses, in terms of theory, then derives the equations governing the physical phenomena and presents modeling techniques. Many of the sample problems, questions, and solved examples were used in CAD courses in many universities around the world. They cover structural analysis, solid mechanics and vibration, steady-state and transient heat-transfer analysis, fluid dynamics, multiphysics simulations, and modeling and meshing. Written and organized so that it can easily be used for self-study, this book guides readers through the basic modeling requirements to the correct and physically meaningful numerical result.

This book provides a methodological framework to set properly the thermal enhancement and energy efficiency in historical buildings during a renovation process. It describes the unique thermal features of historical properties, closely examining how the building materials, structural elements, and state of conservation can impact energy efficiency, including sample calculations and results. It also describes means and aims of several fundamental steps to improve energy efficiency in historical buildings with an experimentation on a case study. This timely text also introduces leading-edge technologies for enhancing the energy performance of historical buildings, including the potential for integration of co- ad tri-generation though micro-turbines, photovoltaics and solar collectors and their compatibility with architectural preservation.
