Rheological behaviour for an anhydrite specimen and determination of its long- time strength

摘要

Based on the method of torsional creep, the creep laws of an anhydrite specimen are studied in this paper. When a shearing stress applied to the specimen is less than a value, only the primary stage takes place. How- ever, when the shearing stress is more than another value, all the three stages of a creep curve, i. e. primary, steady -state and accelerated are exhibited.
