Measurement of Young's modulus of vocal folds by indentation.
OBJECTIVES To assess the accuracy of the indentation method for stiffness measurements and to estimate the Young's modulus of the vocal fold using this technique. STUDY DESIGN Basic science. METHODS Indentation tests were performed using a range of indenter diameters and indentation depths on single- and double-layer silicone rubber models with various cover-layer thicknesses with known geo...
متن کاملMicrostructure continuum modeling of an elastic metamaterial
Elastic metamaterials have unusual microstructures that can make them exhibit unusual dynamic behavior. For instance, if treated as classical elastic solids, these materials may have frequency-dependent effective mass densities which may become negative in certain frequency range. In this study, an approach for developing microstructure continuummodels to represent elastic metamaterials was pre...
متن کاملContinuum elastic modeling of graphene resonators.
Starting from an atomistic approach, we have derived a hierarchy of successively more simplified continuum elasticity descriptions for modeling the mechanical properties of suspended graphene sheets. We find that already for deflections of the order of 0.5 A a theory that correctly accounts for nonlinearities is necessary and that for many purposes a set of coupled Duffing-type equations may be...
متن کاملEnhanced videokymographic data analysis based on vocal folds dynamics modeling
The automatic analysis of temporal patterns of vocal folds motion and the tracking of glottal cues such as folds edge position or glottal area, has recently become a topic of interest in the field of laryngeal video imaging. We discuss here the use of a numerically simulated model of the folds motion within a video analysis context, for the analysis of videokymographic data and glottal cues seg...
متن کاملClassification of speech under stress based on modeling of the vocal folds and vocal tract
In this study, we focus on the classification of neutral and stressed speech based on a physical model. In order to represent the characteristics of the vocal folds and vocal tract during the process of speech production and to explore the physical parameters involved, we propose a method using the two-mass model. As feature parameters, we focus on stiffness parameters of the vocal folds, vocal...
