Fully Implicit RUNGE-KUTTA Schemes for Ideal Elastoplasticity

Schröder, Bettina
Kuhl, Detlef

The present paper derives a multifield formulation of ideal elastoplasticity to enable the consistent application of higher order accurate RUNGE-KUTTA schemes. With the help of an axisymmetric model problem the appearing time discretization errors of distinct schemes are determined and compared.
