Complex frequencies in elastodynamics, with application to the Damping-Solvent Extraction method

Abstract

Abstract This paper addresses the use of complex frequencies in problems of wave propagation and structural vibrations. The most common form of application is as artificial damping that is extracted after the response in the time domain has been obtained. Then again a rather unorthodox application is in the simulation of systems of infinite spatial extent… (More)
