摘要
本文采用三种不同数学模型对螺纹管应力进行有限元计算分析,导出了用修正的平面应变模型计算螺纹管外表面最大应力的计算公式。
Stresses in spirally corrugated tubes are analysed through finite-element calculations using three different maihematic models. A formula for calculating the maximum stress on the outer surface of a spirally corrugated tube using a corrected plane-srrain model is derived.
