Abstract
Solutions are given for several plane elastostatic problems of plates having a V-notch on one edge, and subjected to a variety of boundary conditions. The effect of the magnitude of the V-notch angle and specimen geometry on stress intensity factors K I and K II are obtained for unloaded notch surfaces. There is less than one percent difference in opening mode I stress intensity factor in going from a zero degree notch angle to a 30 degree notch angle.
Notch opening displacements at the plate edge were measured experimentally and the results obtained were in excellent agreement with the computed results.
Résumé
On fournit des solutions à divers problèmes statiques, en conditions planes et élastiques, relatifs à des tôles entaillées en vé sur un de leurs bords et soumises a diverses conditions aux limites.
On examine l'influence de l'ouverture de l'angle de l'entaille et de la géométrie de l'éprouvette sur les facteurs d'intensité de contraintes K I et K II dans les cas où les surfaces de l'entaille ne sont pas sollicitées, et l'on conclut que, lorsque l'angle de l'entaille passe de zéro à 30 degrés, le facteur d'intensité des contraintes K I se modifie de moins d'un pour cent.
Des mesures de déplacement d'ouverture d'entaille ont été effectuées, et les résultats obtenus sont en excellent accord avec les resultats des calculs.
