... that if the consistency mentioned above is guaranteed, then the variable amplitude fatigue computation (such as the ones proposed in commercial codes) is no longer useful. It requires therefore an analysis of the material behavior under variable amplitude loadings in the automotive context. One of the most important...

... to AE are not only along the factional direction. Good correlation was found for wear depth measured in-situ using UMT and post-test using a Tencor profilometer. Testing repeatability was demonstrated. tribology testing coatings automotive friction wear Chao Gao,1Norm Gitis,1Neil Nguyen...

... Recently there has been interest by motor vehicle manufacturers in developing longer-lived automotive engine coolants with an emphasis on organic acid technology (OAT) [1]. Paradoxically, the lifetime of conventional technology remains largely undefined. Concerns arising from the depleting...

... The use of coolant filtration and supplemental coolant additives (SCA) to replenish depleted protective chemistry has been applied in the heavy duty diesel arena for many years. Some filtration of coolant and SCA usage in light gasoline engine and automotive diesel engine vehicles has taken...

... The American Iron and Steel Institute's (AISI) Task Force on Automotive Corrosion is making significant progress in its continuing efforts towards development of an accelerated laboratory test for ranking the cosmetic corrosion resistance of automotive steel sheet products. This paper provides...

..., there is considerable difference in the relative magnitudes and morphologies of corrosion, and occasionally in the relative rankings, as a function of test method. The influence of alloy composition and zinc phosphate coating weight are also discussed. aluminum steel filiform cosmetic corrosion automotive...

... valid survey and characterization of used engine coolant was taken from commercial automotive service centers. The purpose of the survey was to characterize the condition of a typical used engine coolant. The samples were evaluated for suspended matter, and analyzed for pH, reserve alkalinity (RA...

... This paper describes current mechanical property characterization practices for advanced composites in automotive and primarily stiffness-critical aircraft secondary structure applications. The use of extensive costly test programs to develop statistically valid static and fatigue design...
