Finsler geodesics and finite-strain plasticity

Abstract: The theory of energetic rate-independent systems is an elegant way to describe
nonlinear systems in mechanics and other fields. One particular advantage is
that it yields a natural time discretization that consists of a sequence of
minimization problems. Unfortunately, in many interesting cases the objective
functional is only given implicitly as the solution of a second minimization
problem for a curve length in the state space. Therefore, its evaluation and
obtaining derivatives can be very costly. Instead, we present a transformation
based on the Finsler exponential map that turns the second minimization problem
into an initial-value-problem for a second-order ODE. Solutions of this can be
found much cheaper numerically, or may even be available in closed form. We
show examples of this construction, and how to use it to obtain fast and robust
Proximal Newton solvers for finite-strain elastoplasticity.
