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.
A trio of physicists from the University of Rennes, Aoyama Gakuin University, and the University of Lyon have discovered, through experimentation, that it is friction between fibers that allows knitted fabrics to take on ...
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these ...
Metamaterials are artificial materials that do not occur in nature. Their components function like atoms in conventional materials but have special optical, electrical and magnetic properties. Interaction between the components ...
