Abstract: This paper examines the ability to employ the model of a wrinkled thin film coating under plane strain conditions for the generation and manipulation of sounds. It is assumed that the film-on-substrate structure represents a multilevel system consisting of four phases with different elastic properties such as surface layer, film material, interphase and substrate material. The undulation of surface and interface geometry leads to the complex stress state of the film coating resulting from the superposition of two perturbed stress fields evolved near the curved surface and interface. The analysis of the stress state reveals the periodic distribution of the longitudinal stresses smoothly changing from surface to interface. This facilitates the creation of a sound synthesis technique similar to the timbre morphing method which provides the transition between two waveforms while creating new intermediate waveform during this process. The perspective of using the wrinkled thin film model for sound generation is gained by its complex behavior, where the influence of one parameter on the stress distribution is affected by other parameters, which in turn reflects in the rich sound morphologies during the mapping of the stress oscillations onto sound.
Keywords: sound synthesis, physical modeling approach, wrinkled thin film, stress field perturbation.
