摘要：
In present paper the limit load of orthotropic titanium cylindrical shell under internal pressure was studied. By finite element method with twice elastic slope criterion the variations of limit load for orthotropic and isotropic titanium cylindrical shells under different diameter-thickness ratios were investigated. The effect of orthotropic mechanical property on limit load of titanium cylindrical shell was discussed. The difference of limit loads between orthotropic and isotropic titanium cylindrical shells was compared. The results show that the limit loads of orthotropic and isotropic titanium cylindrical shell increase with the diameter-thickness ratio, and the limit load of orthotropic titanium cylindrical shell increases more obviously. The yield strength of circumferential direction for orthotropic titanium cylindrical shell has great effects on the difference of the limit load between the yield strength of isotropic cylindrical shell and the orthotropic titanium cylindrical shell. © 2019 Trans Tech Publications Ltd, Switzerland.
