Abstract

The cleavage fracture behaviour of Charpy V-notch (CVN) and Single Edge Notch Bend (SENB) specimens differ due to the effects of notch root radius, notch depth, notch flank angle and loading rate. This paper presents an experimental and numerical study of the cleavage fracture behaviour of CVN, SENB and a range of non-standard intermediate specimen geometries. The intermediate geometries were selected to provide a basis for quantifying the differences in cleavage fracture behaviour between the CVN and SENB specimens by isolating the individual effects of notch-root radius, notch flank angle and notch depth. Finite element analyses were used to quantify crack and notch-tip stress fields. The study also includes a comprehensive experimental programme covering the range of notch geometries modelled using finite element analysis. The overall aim of the project is to establish links between Wallin's Master Curve for fracture toughness and the common temperature dependence of Charpy energy observed by EricksonKirk et al.
