Surface texture is one of the most important topics in today's world of design, development and performance. As tolerances are shrinking and performance demands are increasing, surface texture is rapidly becoming one of the most important aspects of engine and vehicle performance. Every moving component on a vehicle or engine is influenced by surface texture in one or more of the following ways: vibration, sealing, adhesion, traction, emissions, safety, durability, wear/failure analysis. Many of the industry's top warranty issues (leaks, noise, vibration, etc.) are a direct result of surface texture implications. Rather than focus on the theories of surface texture, this course will focus on the applications of these concepts to automotive applications – thereby giving the attendees tools that they can immediately use as they solve automotive problems such as cylinder bores and emissions control, crankshafts, camshafts and early engine failures, brakes and NVH, wheel bearings and vibration, gaskets and sealing, bearings and durability, pistons and durability, and shaft straightness and vibration.

After more than 40 years of promise, the next decade will see an explosion in the use of composite materials. Aerospace and general aviation have been using the technology for years and automotive and alternative energy markets are now on the cusp of broader implementation. Car manufacturers are already implementing and launching carbon fiber composite development programs and working with both domestic and foreign producers of carbon fibers and composites. With the significant weight savings associated with composites, it is essential for automotive engineers to become knowledgeable about this technology which may revolutionize the way carbon fiber is used in automobiles and ultimately be instrumental in meeting government mandates for fuel economy. This course will provide an overview of different composite materials in terms of material types such as carbon, glass and natural fibers. The focus, however, will be on carbon fiber processes, typical applications, benefits and shortcomings and limitations.

The simultaneous demands for reliability and minimum weight for aircraft and propulsion systems offer some of the most challenging technical problems that structural and safety engineers can encounter. Although much information is available on fracture mechanics and aircraft damage tolerance, this course specifically relates to damage tolerance for gas turbine engines. The need to consider damage tolerance more broadly in new engine designs has just recently been written into FAR 33.70 and new EASA guidelines. With an increasing need for education, both in the U.S. and internationally, this seminar relates directly to the growing interest and priority the AIA, FAA, and engine OEM’s have placed on turbine engine damage tolerance. This two-day seminar offers a broad survey of damage tolerance, one of the many principles behind one of the safest industries in the world. Although the basics of fracture mechanics will be covered, this is not an advanced fracture mechanics course. Attendees will be presented information on how experts in the propulsion community use the principles of prevent, quantify, and improve to keep air travel safe.

The transportation industry, including motor vehicles, aircraft, rail, marine, commercial, off-road and defense vehicles, as well as infrastructures, energy sectors, raw materials, manufacturing, health and food industries all experience significant issues with corrosion which results in billions of dollars of loss each year. Corrosion education and prevention is essential to improve and increase the service life of parts and components which may have a significant impact on the economy of various industries and nations. The focus of this course will be on the fundamentals of corrosion engineering and corrosion prevention of metallic and alloy structures as well as on non-metallic composites and hybrid materials. Recent challenges and opportunities in corrosion of advanced composites used in the automotive, aerospace, and marine industries as well as for underground structures for oil, gas, geothermal and tidal wave technologies will also be included. Different types of corrosion, methods of corrosion protection and prevention, optimum engineering design of corrosion resistance parts and components, standard corrosion tests, responsibilities of corrosion engineers, and a process for setting-up an advanced corrosion laboratory will be discussed.

Canning is the process of mounting the support mat & substrate into the shell. Canning is a very important aspect in the catalyst converter design, especially with the current trend of using thinner wall and ultra-thin wall substrates. Considering the reduced isostatic and shear strengths of thin and ultra thin wall substrates, conventional canning technique will reduce canning durability where the mat or the substrate or the shell may be damaged. This brings into requirement a controlled canning process which shall not disturb the canning durability. The paper shall explain an established controlled canning process developed at a very low investment yet with effective outputs using a DOE methodology for choosing the best suited practices for the respective parts for canning. The outputs were cross verified using push out test and GBD verification using destructive methodology and the results obtained were competitive.

Simulation’s drive towards reality boundary conditions is a toughest challenge. Experience has shown that often the most significant source of error in thermal and dynamic analyses is associated within specified boundary conditions. Typically, validating the system by considering both thermal and dynamic loads with predefined assumptions is time consuming and inconclusive when confronted to reality boundary conditions. Thus, solution comes in unique way of combining thermal and dynamic loads with specified boundary conditions will convey computational results closer to real scenario. As a consequence, strain concentrated regions due to thermal expansion are aggregated more, when coupled with dynamic loading. The stress generated by the coupled analyses will proves to be critical in concerning the durability issue of the hot end system. These conditions were evaluated by a finite elements model through a linear and non-linear approach, which had its results summarized.

There is a potential for metal fatigue in any situation where a component is subjected to cyclic loads. Fatigue failures of various types are a key concern in increasing the reliability of products. Problems involving fatigue have become more severe with the demand for lighter weight structures and components. The effective use of fatigue analysis and predictive tools is critical for reducing the development time of new products. Two methods of metal fatigue analysis will be covered. The first is the stress-life approach. This method is used for high cycle or very long life fatigue problems where loads have fairly constant amplitude. Applications of this method include engine components, gears and shafts. The second method is the strain life approach, which is used for cases involving low cycle fatigue where loads may have a variable amplitude. Applications of this method include suspension and chassis components. The strain-life approach is also more useful when dealing with non-ferrous alloys.
