A Relation to Describe Rate-Dependent Material Failure

Abstract

The simple relation ΏΩ-α = 0, where Ω is a measurable quantity such as strain and A and α are empirical constants, describes the behavior of materials in terminal stages of failure under conditions of approximately constant stress and temperature. Applicable to metals and alloys, ice, concrete, polymers, rock, and soil, the relation may be extended to conditions of variable and multiaxial stress and may be used to predict time to failure.
