Dear friends here is a pdf on engineering material by Dr. S. Singh. Mechanical Engineering Projects/ Seminars/ Paper Presentations.
Dividing his book into four principal p a r t s - - r a w materials, production, properties, and specific engineering materials--Dr.
Nord, Professor of Chemical Engineering at Wayne University, has covered rather thoroughly the subject of engineering materials. In a field of such a magnitude as this, of course, each phase of the subject cannot be investigated completely; but the basic concepts behind each of the four parts into which the book has been divided are presented.
Since the book is intended for college freshman and sophomore use, much more than this is not required. The short first part of the book on the raw materials of engineering presents, as one would expect, the sources, formation and recovery of minerals.
It is really some very elementary physical geology. In the second part, the production of engineering materials from the crude ores are discussed. Mineral dressing, such chemical processes as leaching, calcination, roasting, combustion and the branches of extractive metallurgy--pyrometallurgy, hydrometallurgy and electrometallurgy-- are described.
Beginning with the fundamental states of matter, the mechanical, physical a n d chemical properties of engineering materials are discussed in the third part. The fourth part, with which more than two-thirds of the book is concerned, deals with such specific materials as those for the generation of energy water, fuels and explosives ; ferrous and non-ferrous metals a n d alloys; natural and artificial building stones; natural and synthetic organic materials as wood, rubber and plastics; and protective materials as surface coatings and lubricants.
Each of the various materials is described in some detail.
In the case of the ferrous and non-ferrous materials, for instance, the source, production, properties and uses are discussed. In the case of cementing materials used in building stone construction, the various cements and the chemical reactions occurring during setting are discussed. In the case of rubber, the production, vulcanization, latex processing, the various synthetic rubbers, and the physical properties are discussed.
Robotics is the application of mechatronics to create robots, which are often used in industry to perform tasks that are dangerous, unpleasant, or repetitive. These robots may be of any shape and size, but all are preprogrammed and interact physically with the world. To create a robot, an engineer typically employs kinematics to determine the robot's range of motion and mechanics to determine the stresses within the robot.
Robots are used extensively in industrial engineering. They allow businesses to save money on labor, perform tasks that are either too dangerous or too precise for humans to perform them economically, and to ensure better quality.
Many companies employ assembly lines of robots, especially in Automotive Industries and some factories are so robotized that they can run by themselves. Outside the factory, robots have been employed in bomb disposal, space exploration , and many other fields.
Robots are also sold for various residential applications, from recreation to domestic applications. Main articles: Structural analysis and Failure analysis Structural analysis is the branch of mechanical engineering and also civil engineering devoted to examining why and how objects fail and to fix the objects and their performance.
Structural failures occur in two general modes: static failure, and fatigue failure. Static structural failure occurs when, upon being loaded having a force applied the object being analyzed either breaks or is deformed plastically , depending on the criterion for failure.
Fatigue failure occurs when an object fails after a number of repeated loading and unloading cycles. Fatigue failure occurs because of imperfections in the object: a microscopic crack on the surface of the object, for instance, will grow slightly with each cycle propagation until the crack is large enough to cause ultimate failure.
Some systems, such as the perforated top sections of some plastic bags, are designed to break. If these systems do not break, failure analysis might be employed to determine the cause. Structural analysis is often used by mechanical engineers after a failure has occurred, or when designing to prevent failure.
Engineers often use online documents and books such as those published by ASM  to aid them in determining the type of failure and possible causes. Once theory is applied to a mechanical design, physical testing is often performed to verify calculated results. Structural analysis may be used in an office when designing parts, in the field to analyze failed parts, or in laboratories where parts might undergo controlled failure tests.
Thermodynamics and thermo-science[ edit ] Main article: Thermodynamics Thermodynamics is an applied science used in several branches of engineering, including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. As an example, automotive engines convert chemical energy enthalpy from the fuel into heat, and then into mechanical work that eventually turns the wheels.
Thermodynamics principles are used by mechanical engineers in the fields of heat transfer , thermofluids , and energy conversion. Mechanical engineers use thermo-science to design engines and power plants , heating, ventilation, and air-conditioning HVAC systems, heat exchangers , heat sinks , radiators , refrigeration , insulation , and others.
A technical drawing can be a computer model or hand-drawn schematic showing all the dimensions necessary to manufacture a part, as well as assembly notes, a list of required materials, and other pertinent information.
Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions.
Optionally, an engineer may also manually manufacture a part using the technical drawings. However, with the advent of computer numerically controlled CNC manufacturing, parts can now be fabricated without the need for constant technician input.
Manually manufactured parts generally consist spray coatings , surface finishes, and other processes that cannot economically or practically be done by a machine. Drafting is used in nearly every subdiscipline of mechanical engineering, and by many other branches of engineering and architecture. Modern tools[ edit ] An oblique view of a four-cylinder inline crankshaft with pistons Many mechanical engineering companies, especially those in industrialized nations, have begun to incorporate computer-aided engineering CAE programs into their existing design and analysis processes, including 2D and 3D solid modeling computer-aided design CAD.
