Analysis of Failure Emanating from a Notch

  • Published:
Materials Science Aims and scope

Notch-like defect assessment cannot be done by using classical fracture mechanics (mechanics of cracks). In order to prevent overconservatism, the concepts of notch fracture mechanics, such as notch stress intensity factor or notch energy integral Jρ are generally used for this purpose. A local stress criterion, named volumetric method, defines effective stress. It is used for more advanced assessment when introducing geometry and constraint effects. These effects are taken into account for notch fracture toughness and constraint a modified notch failure-assessment diagram.
