In addition, in order to convenient mathematical treatment, the traditional methods adopt the form of the third strength theory in the simple but be safe to get equivalent stress, and assuming the same cylinder material in each layer.
The methods and procedures when handing stresses such as the use of complex issues that multi-cylinder, cylinder layers of different materials or different allowable, and does not increase the difficulty.
Therefore, in accordance with the principle of equal strength, the equivalent stress value of σe1, σe2, σe3 of the wall in the inner cylinder, middle cylinder and outer cylinder should be all equal to allowable stress [σ], so that makes the stress distribution of combination cylinder tend to be more uniform, each part of the materials can be used most effectively.
