A simplified approach for assessing the leak-before-break for the flawed pressure vessels

摘要

Surface cracks or embedded cracks in pressure vessels under service may grow and form stable through thickness cracks causing leak prior to failure. If this leak-before-break phenomenon takes place, then there is a possibility of preventing the vessel failure. This paper presents a simplified approach for assessing the leak-before-break or failure of the flawed pressure vessels. This approach is validated through comparison of existing test data.
