Modeling and validation of the elasticity parameters of multi-layer specimens pertinent to silicone vocal fold replicas

Deformable silicone-molded multi-layer vocal folds replicas are commonly used in physical studies of auto-oscillation. Nevertheless, few deal with the reproducibility or mechanical properties silicone moldings. In current study, effective elastic Young’s modulus molded bone-shaped specimens consisting parallel and serial stacked layers is sought. The each layer pertinent for one anatomical whereas dimensions designed so that dimension ratio between adjacent varies range observed on human folds. one-layer, two-layer three-layer then determined experimentally (between 4 kPa 65 kPa) uni-axial press tests precision loading both methods cross-validated (difference less than 3.5 kPa). overall molding accuracy (1.5 mm) has no significant impact (less 1.2 sought procedure considered reproducible. Furthermore, an analytical model approach specimen validated (overall 2.4 against experimental data.
