Abstract

A method tsing photoelastic coatings and high speed photography is described for determining K1C values for brittle cracks propagating through mild steel plates. The increase of K1C with crack velocity at high crack velocities is discussed.

Résumé

En recourant aux vemis photoelastiques est à la technique de photographie à grande vitesse, ou a mis an point une méthode permettant de determiner les valeurs de K1C dans le case de ruptures fragile se propagenat dans des toles d'acier doux.

On discute l'accroissement de K1C en fonction de la vitesse de propagation des fissures pour ies valeurs élevées de celle-ci.

Zusammenfassung

Eine methode wird beschrieben, bei der der Gebrauch von photoelastischen Belagungen und von Hochgeschwindigkeits Photographie benutzt wird um die K1C Werte der sich fortsetzenden Sprödbrüche in mildem Stahl fesmustellen. Das Ansteigen der K1C mit Rissgeschwind igkeit bei hohen Rissgeschwindigkeiten wird besprochen.
