Abstract: Tires are the only means for connecting a vehicle to the ground. The forces such as driving force, braking force, rotation force and the like occur on the contact surface between the tire and the ground and thus determine the motion of the vehicle. A general tire generates separation that continues to repeat tension and compression by the load of the vehicle. The separation raises the temperature of the tire, resulting in loosening between tire members and in the end damages the tire. Since a tire has a composite structure, which consists of rubber and reinforcements, many problems arise in the analysis of the tire. In this study, a tire of a composite structure was analyzed for heat transfer under the same condition as in the running state, so as to examine temperature distribution at tread. Theoretical results were verified using a thermal vision camera a non-contact non-destructive temperature measurement instrument.

Abstract: In a primary reactor cooling system(RCS), a dissimilar weld zone exists between austenitic-ferritic duplex cast stainless steel(CF8M) in a pipe and low-alloy steel(SA508 cl.3) in a nozzle. Thermal aging is observed in CF8M as the RCS is exposed for a long period of time to a reactor operating temperature between 290 and 330°C, while no effect is observed in SA508 cl.3. An investigation of the effect of thermal aging on the various mechanical properties of the dissimilar weld zone is required. The purpose of the present investigation is to find the effect of thermal aging on the dissimilar weld zone. The specimens are prepared by an artificially accelerated aging technique maintained for 100, 300, 900, 1800 and 3600 hrs at 430°C, respectively. The various mechanical tests for the dissimilar weld zone are performed for virgin and aged specimens.
