Wave reflection at the interface between a nonlinear discrete lattice and a matching linear system

This contribution considers the wave reflection at the interface between a discrete lattice that describes the nonlinear near-field response to a dynamic load and a matching system that describes the linear far-field response. The near-field system is modelled as a one-dimensional discrete system of particles that is capable of describing...

A mixed time-frequency domain method to describe the dynamic behaviour of a discrete medium bounded by a linear continuum

To minimize the calculation time required by numerical models that de- scribe dynamic interactions involving nonlinear behaviour, it is useful to divide the model into two separate domains. One domain close to the interaction point, which consists of a sophisticated model capable of describing nonlinear phenomena, and another domain at a...
