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. WebFigure 3 shows that the calculated elastic constants vary linearly with pressure over the range of hydrostatic pressures up to 40 GPa. The slope of the linear ﬁts as a function of …
