Abstract

The possibility of estimatingK Id at the NDT from the crack geometry and load conditions used in the drop-weight (NDT) test has been re-examined. Theory and experiment support the usefulness of the relationK Id yd = 0.075 □m at the NDT temperature.

Résumé

On ré-examine les possibilités d'estimer la valeur deK Id à la température NDT déterminée par l'essai drop-weight en se basant sur la géométrie de la rupture et sur les conditions de la mise en charge.

L'approche théorique et les résultats expérimentaux souiignent la pertinence de la relation.K Id yd = 0.0075 m 1 2 à la température NDT, dans le cas des aciers de qualité navale.
