Abstract.
Simulating wear testing of implants under cyclic loading requires a
multiscale approach in time. Simple cycle jumping realizes an explicit
Euler scheme for the averaged evolution of the shape. In this talk, we
consider spectral deferred correction methods for higher order integration,
and exploit the accuracy-effort trade-off available in finite element based
simulations. This leads to inexact SDC methods, which can be much more
efficient than standard SDC approaches. Based on work and accuracy models,
a theoretically optimal choice of inexactness is derived. The efficiency of
the resulting method is illustrated in some numerical examples.
