The effect of stress concentration, arising from formation of pitting corrosion holes, on the strength and service life of a material is discussed. Formulas are derived for calculating the stress concentration factor in a plate containing a shallow round corrosion hole. A case study is presented showing the effect of the corrosion hole depth on the stress concentration factor and the burst pressure.
