Title: Dynamic performance of bimaterial composite sphere under spherical wave.
Authors: Zhang, Xi-Meng1,2 (AUTHOR) zhangximeng@hrbeu.edu.cn, Qi, Hui3 (AUTHOR)
Source: Mechanics of Advanced Materials & Structures. 2024, Vol. 31 Issue 18, p4423-4442. 20p.
Subjects: Spherical waves, Separation of variables, Stress concentration, Algebraic equations, Finite element method, Spheres
Abstract: In this article, the dynamic characteristics of bimaterial composite spheres under spherical waves induced by cyclic pressure are studied. First, on the basis of the Lamb Decomposition and Variable Separation method, the analytical expression of spherical wave is conducted, which satisfies the stress equilibrium on the outer and inner surfaces of the sphere. Next, algebraic equations with respective boundary conditions are composed and solved by Legendre Polynomial expansion and effective truncation techniques. Obtained results enable to reveal the influence on the dynamic stress concentration factor intensity under proper conditions. The conclusions of this article are verified by comparing the analytical solutions to the ones obtained by the finite element method. This article can provide a theoretical method for the analysis of mechanical properties of multilayered spherical structure under dynamic loading. [ABSTRACT FROM AUTHOR]
