Which one of the following statements regarding rock deformation and strength is correct?
A)Rupture and plastic deformation occur when stresses and strain rates exceed the elastic limit of a material.
B)Rocks undergo plastic deformation less readily as temperatures and pressures increase.
C)Elastic deformation is accomplished through internal flow of material.
D)When rocks are subjected to stress for long time spans, very small, plastic deformations accumulate to produce large, permanent, elastic deformations.

Question

Quizplus · Accepted Answer

Rupture and plastic deformation occur when stresses and strain rates exceed the elastic limit of a material. This means that if the stress and strain rates continue to increase beyond the elastic limit, the material will eventually break or deform permanently. This is a fundamental principle of rock mechanics and is applicable to all types of rocks, regardless of their temperature or pressure conditions.
