Evaluation of Fracture Toughness by Chevron V-Notch Method

The chevron notch (CN) method has an advantage that the crack length need not be measured to estimate fracture toughness. The crack, however, should grow stably until the critical length to get the valid fracture toughness value, which was hardly attained by a conventional CN method. Therefore, a ch...
