proportional limit
The greatest stress that a material is capable of withstanding without deviation from proportionality of stress to strain (Hooke's law). In the case of rocks, this term and "elastic limit" are restricted to short-time tests; rocks may slowly and permanently deform in periods of long duration, even at stresses below the short-time proportional limit.
