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.
If a liquid is cooled slowly to its freezing point, it becomes a crystal in which the constituent particles are arranged in an ordered pattern. In contrast, when the liquid is cooled very quickly, the particles are unable ...

Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can "remember" past mechanical ...

One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner ...
From chewing to chomping to grinding, teeth suffer from a lifetime of repeated mechanical stress. It makes sense, then, that enamel is one of the hardest natural materials.
