摘要
基于弹粘塑性本构关系 ,讨论了附加振动时单轴拉伸的应变及应力变化过程。分析结果表明 ,本文所给出的力学模型 。
Based on the elasto viscoplastic constitutive equation, the history of stress and strain is analyzed during uniaxis tension under oscillatory loading. The analytical results show that the model developed in this paper well reflects such known experimental facts of stress overshooting and mean stress decreasing reported in existing papers.
