Description

Fractographic analyses of several cracked weldments from pressure vessel fabrications of ASTM A515 Grade 65 carbon steel plates are presented. Two distinct modes of plate cracking--classical lamellar tearing and abrupt brittle fracture--are observed. A model using the fracture mechanics approach is developed to explain the two modes of cracking. Based on this, a screening criterion for the plates using conventional tensile and Charpy impact tests in the through-thickness direction of the plates is proposed
