Optimization and sound absorption modeling in Yucca Gloriosa natural fiber composite

Introduction: Nowadays, the acoustic behavior analysis of natural fibers composites has received increasing attention by researchers. In this regard, the present study aimed to optimize and model the sound absorption behavior of composites made of Yucca Gloriosa (YG) fiber via using a mathematical modeling approach. Methodology: In this experimental cross-sectional study, in order to fabricate...

Sound Wave Propagation in a Multiferroic Thermo Elastic Nano Fiber Under the Influence of Surface Effect and Parametric Excitation

This study investigates that the sound wave propagation of multiferroic thermo elastic Nanofibers under the influence of surface effect and parametric excitation via Timoshenko form of beam equations. The equation of analytical model is obtained for Nanofiber through shear and rotation effect. The solution of the problem is reached through the coupled time harmonic equations in flexural directi...
