ISO 12135 – Quasistatic Fracture Toughness for Metallic Materials
ISO 12135 specifies methods for determining fracture toughness in terms of K, ?, J and R-curves for homogeneous metallic materials subjected to quasistatic loading.
Specimens are notched, precracked by fatigue and tested under slowly increasing displacement.
*** Before conducting this ISO standard , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
