摘要: 以经典的热弹塑性蠕变理论为基础,考虑到材料常数随温度的变化,导出了热弹塑性蠕变问题的增量本构方程和轴对称有限元计算公式,编制了程序,并以高温炉管为例作了应力、应变计算,结果可供工程设计部门参考。

Abstract: Based on the theory of thermo-elastic-plastic creep, and considered the material properties changed with temperature, the incremental original equations of thermo-elastic-plastic creep, and the calculation formulas of axisymmetric finite element method are presented. The stress-strain of the boiler pipe with elevated temperature is analysed and the calculation results may be refered by engineering design department.

Key words: Creep, Finite element method, Thermo-elastic-plasticity
