Therefore, in terms of the cylindrical shell with interior structures, developing an efficient approach which combines advantages of the analytical method and numerical method is meaningful. Unfortunately, owing to the complexity involved in the coupling of the two methods, the number of researches on...
Consider an elastic circular cylindrical shell phononic crystal with a unit-cell of length d, as sketched in Fig. 1. The circular cylindrical shell model is formulated with the semi-analytical SE method presented in Section 2. The equilibrium equation for the finite circular cylindrical shell by ...

These problems involve the minimax deflection and minimal compliancy of a cylindrical shell. Expressions of the objective function can be obtained by a stepped reduction method. In minimizing the maximum deflection, the position of the maximum deflection from the previous iteration is used as the ...
