Summary
An isotropic theory of plasticity is proposed in which expansion, rotation and translational movement of the yield surface are taken into account. The properties of the anisotropic parameters are investigated for some measured data. The incremental constitutive equation is then derived. The resulting constitutive equation is used to predict the shapes of subsequent yield surfaces.
Übersicht
Es wird eine anisotrope Plastizitätstheorie vorgeschlagen, die auf der kinematischen Verfestigung aufbaut, aber gleichzeitig die Dehnung, Verschiebung und Rotation der Fließfläche berücksichtigt. Die Eigenschaften der anisotropen Koeffizienten werden für einige experimentelle Ergebnisse untersucht. Dann wird die inkrementelle Stoffgleichung hergeleitet. Sie wird zur Bestimmung der folgenden Fließflächen angewendet.
