... toughness, pipe steel, test method INTRODUCTION The crack tip opening angle (CTOA) has been proposed as a material parameter for control of fast ductile fracture propagation and arrest of axial cracks in pipelines for at least 25 years [1-3]. It has become of special interest with the introduction of high...
