8、fracture originating from cracks or crack-like stress concentrators. The methods are intended for specifications of acceptance and manufacturing quality control when there is a sound basis for establishing a minimum acceptable sharp-notch strength. These methods are restricted to such material where

9、 a sharp notch can be machined to a radius of 0,018 mm or less. 2 References EN 2002-1 Aerospace series - Test methods for metallic materials - Part 1 - Tensile testing at ambient temperature i) EN 2002-2 Aerospace series - Test methods for metallic materials - Part 2 - Tensile testing at elevated t
