Anisotropy of multi-layered structure with sliding and bonded interlayer conditions

Lingyun YOU, Kezhen YAN, Jianhong MAN, Nengyuan LIU

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 3, Pages 632-645 doi: 10.1007/s11709-020-0617-4

Abstract: A better understanding of the mechanical behavior of the multi-layered structure under external loading is the most important item for the structural design and the risk assessment. The objective of this study are to propose and develop an analytical solution for the mechanical behaviors of multi-layered structure generated by axisymmetric loading, and to investigate the impact of anisotropic layers and interlayer conditions on the multi-layered structure. To reach these objectives, first, according to the governing equations, the analytical solution for a single layer was formulated by adopting the spatial Hankel transform. Then the global matrix technique is applied to achieve the analytical solution of multi-layered structure in Hankel domain. The sliding and bonded interlayer conditions were considered in this process. Finally, the numerical inversion of integral transform was used to solve the components of displacement and stress in real domain. Gauss-Legendre quadrature is a key scheme in the numerical inversion process. Moreover, following by the verification of the proposed analytical solution, one typical three-layered flexible pavement was applied as the computing carrier of numerical analysis for the multi-layered structure. The results have shown that the anisotropic layers and the interlayer conditions significantly affect the mechanical behaviors of the proposed structure.

Strategic Study of CAE 2007, Volume 9, Issue 8, Pages 88-91

Abstract:

In order to study the residual stresses of auto fettage super high pressure vessel effectively, a new model of stress and strain was developed in this paper. The model is more closer to actual working condition for the steel applied in auto fettage super high pressure vessel through the strict mathematic testification. The example to be given in this paper states how this model was established and how the error was analyzed. The same example also shows that solving the new model of stress and strain based on general tensile curves is feasible and reliable indeed. The model has theoretical signification and engineering practical value to a certain extend.
