Mechanical deformation as a research area investigates the response of materials to applied stresses and strains, focusing on the underlying mechanical, microstructural, and thermodynamic processes that govern elastic, plastic, viscoelastic, and viscoplastic behavior. It encompasses experimental, theoretical, and computational studies of phenomena such as dislocation motion, twinning, fracture, creep, fatigue, and strain localization across length scales from atomic to macroscopic. This field supports the development of constitutive models, structure–property relationships, and advanced characterization methods, enabling prediction and optimization of mechanical performance in metals, polymers, ceramics, composites, and biological or complex engineered materials under diverse loading and environmental conditions.
The popularity of wearable electronics has induced demand for their parts, including power sources such as triboelectric nanogenerators (TENGs). Such power sources must be both stretchy and high-performance, holding up under ...
