Résumé

Dans la mesure où le modèle de Dugdale est un modèle approximatif pour l'analyse pseudo élastoplastique, l'auteur propose une méthode simple pour estimer les dimensions de la zone plastique se trouvant en avant de l'extrémité d'une fissure.

Zusammenfassung

Da das Dugdale Modell ein annäherndes Modell för pseudo elastisch plastische Analyse ist, kann man das folgende Verfahren zur Bewertung der Abmessungen der plastischen Zonen an der Spitze eines Risses ziemlich rechtfertigen.
