We discuss a semi-implicit numerical scheme that allows for minimizing the bending energy of curves within certain isotopy classes. To this end we consider a weighted sum of a bending energy and a so-called tangent-point functional. We define evolutions via the gradient flow for the total energy within a class of arclength parametrized curves, i.e., given an initial curve we look for a family of inextensible curves that solves the nonlinear evolution equation.

In this talk, we will focus on the port-Hamiltonian modeling of piezoelectric material and the corresponding structure preserving discretization methods. We will show that modeling choices influence the stabilizability properties. In addition, we will treat shape control of a piezoelectric Timoshenko beam.

Discretization converts infinite dimensional mathematical models into finite dimensional algebraic equations that can be solved on a computer. This process is accompanied by unavoidable information losses which can degrade the predictiveness of the discrete equations.
