Summary
TheLèvy-Mises equations for an ideal plastic material are derived from a general implicit relation between the stress and rate of deformation tensors. This derivation provides an alternative to the usuala priori postulates of a yield criterion and flow rule.
Zusammenfassung
DieLèvy-Mises-Gleichungen für ein ideal plastisches Material wurden aus einer allgemeinen impliziten Beziehung zwischen dem Spannungstensor und dem Tensor der Deformations-geschwindigkeiten hergeleitet. Diese Herleitung bietet eine Alternative zu den üblichena priori Postulaten einer Fließbedingung und eines Fließgesetzes.
