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.
I've always been fascinated by how materials break down, especially glasses and polymers that don't have a regular crystal structure. Unlike crystals, where we understand plasticity through things like dislocations, amorphous ...
The Kaiser effect, which is known as a stress memory effect, predicts that seismic events occur only when the previous maximum stress is exceeded. Therefore, the Kaiser effect has been applied for the estimation of the magnitude ...
