An understanding of how residual stresses due to overloads effect stress intensity factors for fatigue cracks at common stress concentrators, such as holes, is important. In this paper a weight function approach is used to determine stress intensity factors for cracks in residual stress fields, due to three types of o…

The effect of co-existing organics on the selective reduction of NO using ammonia as a reducing agent was investigated over Cu/ZSM-5 catalysts. Addition of organics in the feed gas resulted in deactivation of the catalysts. NH3-SCR activity at 200°C decreased in the following order, acetaldehyde > n-decane > methyl de…
