Reliability of an elastic bar under tension in a corrosive environment

Isaac Elishakoff and Clement Soret

Abstract

In this study we investigate the reliability of a bar subjected to a random tensile load in presence of corrosion. We consider linear, quadratic and exponential models that connect the stress in the bar with the corrosion rate. Two probability densities are considered for the load, with attendant derivation of the time-dependant reliability. The design time of operation is determined utilizing the requirement that the reliability must not be less than the required value.

Key Words

reliability; corrosion; bar; time to failure
