| Abstract: | A three-element composite piping made of elastic materials was studied with finite element numerical simulation. Utilizing structural stress analysis of ANSYS software, some characteristics for the interfaces of the composite piping were numerically modeled and the effect of variation of their physical parameters on mechanical properties of the composite piping was analyzed as well. The numerical analysis results showed that the reasonable adjustment of Young's modulus and Poisson's ratio of ceramic intermediate layer formed in the three-element composite piping could reduce the interfacial stress between layers so that the service life and safety reliability of the three-element composite piping would be improved. |
