Quasi‐Newton waveform iteration for partitioned surface‐coupled multiphysics applications [PDF]

International Journal for Numerical Methods in Engineering, 2020
SummaryWe present novel coupling schemes for partitioned multiphysics simulation that combine four important aspects for strongly coupled problems: implicit coupling per time step, fast and robust acceleration of the corresponding iterative coupling, support for multirate time stepping, and higher‐order convergence in time.

Frequency tuning, nonlinearities and mode coupling in circular graphene resonators

, 2013
We study circular nanomechanical graphene resonators by means of continuum elasticity theory, treating them as membranes. We derive dynamic equations for the flexural mode amplitudes.
