nearelastic
Nearelastic is a term used to describe materials or constitutive models that exhibit near-elastic behavior. In this context, near-elastic refers to a mechanical response that is predominantly elastic over a substantial portion of the strain range, with small, recoverable deviations from a perfectly linear elastic relationship and minimal energy dissipation under cyclic loading.
The defining characteristics of nearelastic behavior include a nearly linear stress–strain curve with slight nonlinearity at
Modeling approaches for nearelasticity typically involve incremental stiffness that evolves with strain, along with a small
Applications of nearelastic concepts appear in precision engineering, lightweight structural components, and vibration-damping devices, where predictable
