Exact Solution of Axial Stress for a Multilayered Pressure Vessel Subjected to Mechanical and Thermal Loads

Article Preview

Abstract:

At present, limited work was reported on the exact solution of axial stress for a multilayered pressure vessel subjected to mechanical and thermal loads. However, the axial stress plays an important role to the structural strength due to the influence of thermal load. Based on the theory of thermo-elasticity and finite element (FE) technology, therefore, the exact solution and numerical solution were constructed for a multilayered urea synthesis tower made of different kinds of materials subjected to an internal pressure and a thermal load. Results show good agreement between the theoretical solution and numerical solution, and thus it demonstrates the reliability of the derivation process and developed calculation formula, which would be helpful for more precise calculation and scientific design of the multilayered pressure vessel.
