摘要：

Rapid creep, as observed originally by Andrade, increases as the cube root of time. An explanation is proposed, based on the concept of volumes of correlated strain increment in the material, each triggered by a microscopic thermal activation. As the creep strain increases, the ensuing work hardening reduces the correlation volume that can be produced by a given thermal fluctuation.
