The Study of CTOD Test and Allowable Value

Article Preview

Abstract:

In order to determine the heavy plate structure have sufficient fracture toughness, based on BS7448 fracture toughness test experiment standard,the study of the typical bridge steel material were extended to CTOD( crack tip open displacement) fracture toughness test at 20 °C, The average CTOD value of base metal which was more than the allowable value of CTOD were obtained,so the structure can satisfy the design need .
