底部减薄三通管件塑性极限内压的有限元分析

Finite Element Analysis of Plastic Limit Internal Pressure for Tee Pipe Joints with Bottom Thinning

采用有限元分析研究了单一内压作用时局部减薄缺陷对三通管塑性极限内压的影响。总结出含底部缺陷三通管的塑性极限载荷随缺陷尺寸影响的变化规律。

Based on the finite element analysis, the effect of bottom thinning defects to plastic limit internal pressure of tee pipe joints with single internal pressure was analyzed. And the change rule of plastic limit load for tee pipe joints containing bottom thinning defects with flaw sizes was obtained.
