On the general equations of axisymmetric problems of ideal plasticity. (English) Zbl 0548.73017

Summary: Introducing a velocity potential, we reduce the fundamental equations of axisymmetric problems of ideal plasticity to two nonlinear partial differential equations. From these equations we discuss compatibility of the Harr-Kármán hypothesis with von Mises yield criterion and the associated flow law.
