Resembling John Ford’s Monument Valley In the matter of constraint effects on notch-induced fracture of cold drawn pearlitc stee, Fig. 8 shows the fracture profile in a sharply notched sample of a moderately cold drawn pearlitic steel (steel A3 that has undergone 3 cold drawing steps, cf. Fig. 1; specimen B with the maximum level of stress triaxiality/constraint, cf. Fig. 2), together with a picture of Monument Valley in the USA. As the picture of the left-hand side resembles that of the right-hand side, such a special fracture path appearing in sharply notched samples of cold drawn pearlitic steel will be noted as Monument Valley Profile , a term coined by Toribio (2018b).
