Sound absorption properties of natural Bari bamboo composite

Proceedings of the Institution of Mechanical Engineers Part L Journal of Materials Design and Applications, Год журнала: 2025, Номер unknown

Опубликована: Фев. 28, 2025

This study investigates the sound absorption properties of Bari bamboo (Bambusa polymorpha) composites, using crumb rubber from waste tires and polyurethane binder (PU Binder). The objective is to evaluate acoustic panels made different culm parts—internode node fibers—and combinations with air gaps. samples’ coefficient (SAC) was measured two-microphone impedance tube transfer function method. Results indicate that diaphragms achieve a SAC peak over 0.9 at frequencies below 960 Hz. incorporation significantly improves lower frequencies, gaps shift even frequencies. demonstrates reinforced rubber, can be sustainable effective alternative synthetic sound-absorbing materials. highest values were obtained consolidated which exhibited enhanced performance. introduction an gap further optimized work highlights potential utilizing natural, biodegradable materials like combined waste-derived for applications, offering environmentally friendly solution noise control.

Rheology-dependent surface wave characteristics in an advanced geomaterial flexoelectric plate with viscoelastic coating

Physica Scripta, Год журнала: 2024, Номер 100(1), С. 015232 - 015232

Опубликована: Ноя. 27, 2024

Abstract This study investigates the transmission of seismic surface waves in a composite framework comprising viscoelastic layer overlying flexoelectric material. The focuses on understanding impact different models (Maxwell, Newtonian, and Kelvin-Voigt) interface conditions (smooth welded contact) damping dispersion characteristics these waves. To achieve this, employs variable-separable technique appropriate boundary to derive complex frequency relations for electrically open short circuits scenarios. These are subsequently divided into real imaginary parts examine dampening properties, respectively. Numerical simulations conducted analyze response coefficient, thickness, bonding parameter phase velocity coefficient. research findings indicate that attenuation properties Maxwell Newtonian lower compared Kelvin-Voigt model. Graphical comparisons highlight influence wave propagation. can help development sensors, energy harvesters, manipulation devices employ materials with coatings. Knowledge dynamics structures is vital their optimal performance.

Rubber-sand infilled soilbags as seismic isolation cushions: experimental validation

Geosynthetics International, Год журнала: 2024, Номер unknown, С. 1 - 14

Опубликована: Март 23, 2024

This study proposes soil bags filled with a rubber sand mixture (SFRSM) to enhance the stability of layers for effective seismic isolation. To evaluate dynamic characteristics SFRSM, large-scale cyclic simple shear tests were conducted investigate effects content, vertical pressure, displacement amplitude, fill percentage, and laying scheme. Furthermore, shaking table carried out impact vibration intensity frequency on isolation SFRSM layers. The results indicate that (1) exhibits lower modulus higher damping than traditional rubber-sand layers, suggesting superior energy dissipation capabilities. (2) influenced by percentage scheme, indicating potential creating resilient isolators suited various conditions. (3) isolating efficacy is due its high-frequency vibrations, threshold reducing as more are implemented. In summary, these experimental provide evidence proposed innovative strategy enhances strength stiffness original layer, making it well-suited design applications in low-rise buildings less-developed regions.
