This paper aims at studying the stress state transition in cracked plates with V‐shaped and U‐shaped notched configurations subjected to tension loading. The transition is established on the basis of the h‐stress triaxiality parameter. Stress triaxiality profiles along the crack front are computed via three‐dimensional linear‐elastic finite‐element models. Overall, the introduction of notches increases the h‐stress triaxiality level and speeds up the transition. This means that the surface region of the notched geometries is always larger than that of the unnotched configurations. Therefore, the extent of the surface region of the unnotched cracked plates can be used an upper bound.
