In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to plasticity, in which the object fails to do so and instead remains in its deformed state. WebOct 14, 2024 · In a confined domain, the temporal stability analysis indicates (a) the destabilizing influence of the inertial terms, (b) the destabilizing impact of the finite boundaries near the wall, and (c) the stabilizing …
