Diagnostics of fracture mechanisms of structural steels by acoustic emission

This work investigates the fracture mechanisms upon static tension of flat specimens of structural steels of Russian grade 09G2 and steel of Russian grade K3, which are widely applied in the oil and gas industry, in the defect-free state and after growing of an artificial defect in the form of a fat...

Description
Summary:This work investigates the fracture mechanisms upon static tension of flat specimens of structural steels of Russian grade 09G2 and steel of Russian grade K3, which are widely applied in the oil and gas industry, in the defect-free state and after growing of an artificial defect in the form of a fatigue crack using an SDS1008 acoustic emission diagnostic system and fractographic analysis of fracture surface.
