A model for anelastic relaxation controlled cyclic creep

摘要: In the paper we derive an expression for cyclic minimum strain rate of creep in systems where anelastic relaxation is a controlling mechanism. The behavior modeled by assuming that recovered during off-load periods must first be stored on-load before nonrecoverable results. To perform derivation, time dependence reported two oxide dispersion strengthened alloys and shown to adequately described double exponential function. then incorporated into expression, generally used describe static data, obtain frequency rate. predicted values derived using results from tests are excellent agreement with experimentally observed use no adjustable parameters. proposed model storage delaying also consistent effects temperature maximum load on
