    We present a novel equation of motion for a nonlinear gradient elasticity model. Thereby, higher-order gradient terms are introduced to capture the effect of small-scale soil heterogeneity/micro-structure. Using a newly established finite difference scheme, corresponding solutions including stationary waves are determined. In comparison with a commonly used model for nonlinear seismic waves, which has leading derivatives of second order, the solutions of the novel equations are much smoother. This allows much more accurate numerical computations as well as more realistic predictions of the seismic waves.

    The dynamics of a novel multibody wave energy converter based on inclined single modules connected to a frame are investigated, on which generators convert the corresponding relative motion into electrical power. Thereby, it is studied under which conditions the inclined individual modules perform the largest relative motions in regular and irregular waves. For this, different setups are analyzed in the presence of wave excitations, which is generated by a random non-white Gaussian stochastic process.
