Mechanical and acoustical properties as a research area focuses on characterizing and modeling how materials and structures respond to mechanical loads and acoustic waves, including stress–strain behavior, elasticity, viscoelasticity, damping, wave propagation, impedance, and sound absorption or transmission. It integrates solid mechanics, continuum mechanics, and acoustics to understand couplings between structural dynamics and sound fields, often using experimental techniques such as dynamic mechanical analysis, ultrasonic testing, and impedance tube measurements, alongside analytical and numerical methods (e.g., finite element and boundary element modeling). This research underpins the design and optimization of materials and systems for vibration control, noise reduction, ultrasonic devices, and acoustic metamaterials.
Phononic crystals (PnCs) are artificial structural composites with periodic modulation of elastic parameters, and they are capable of regulating the propagation of sound waves. Devices with different geometric parameters ...
