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.

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.

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.

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.

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.

This specification covers an aircraft quality, low alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. These products have been used typically for parts requiring a combination of high tensile strength and good ductility with relatively high impact strength and hardness, but usage is not limited to such applications. Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking after heat treatment. ARP1110 recommends practices to minimize such conditions.
