通过对应力松弛的物理模型分析 ,推导出高温螺栓 -法兰连接时 ,在考虑法兰弹性变形和蠕变对螺栓松弛影响的情况下 ,时间t和应力σ的关系式。
Through the analysis of the physical model of stress relaxation, the relation between the time t and the stress σ under the condition of high temperature bolt-flange connection is deduced in consideration of the influence of flange’s elastic deformation and creep on bolt’s relaxation.
