Energy density fracture criteria for cracks under mixed mode loading
Description
The strain energy density fracture criterion for crack initation under mixed mode static loading is extended with respect to brittle and ductile fracture taking into account results of metal-physical investigations. The energy density factors Sd (distortion), Sv (dilatation) of the inhomogeneous (cracked) continuum are correlated with the equivalent stresses sigmad, sigmav of the homogeneous (non-cracked) continuum. Recent experimental results are used for comparison. (orig.)
Abstract (German)
Das Formaenderungs-Energiedichte-Kriterium fuer die Vergroesserung allgemein beanspruchter und geneigter Risse bei statischer Belastung wird ausgehend von metallphysikalischen Befunden im Hinblick auf sproedes und duktiles Bruchverhalten erweitert. Der Zusammenhang zwischen den Energiedichtefaktoren Sd (Distorsion), Sv (Dilatation) des inhomogenen (Riss-) Kontinuums und den Vergleichsspannungen sigmad, sigmav des homogenen Kontinuums wird hergestellt. Neuere experimentelle Ergebnisse werden zum Vergleich herangezogen. (orig.)Additional details
