Abstract: Based on the nonlinear theory of thin elastic shells and fundamental equations of the fluid mechanics, the formulas of fluid-solid interaction relation for a penetrative shell in fluid are established provided that orifices are too small to ignore the effects on the shell rigidity and the fluid action to the shell. The united Euler-Lagrange method is chosen to construct the equations for a slightly bending cylindrical shell with orifices. As an example, the deformation and the distribution of internal forces of the shell are evaluated, and the effects of the variety of concerned parameters are discussed.
Keywords: fluid-solid interaction, united Euler-Lagrange method, cylindrical shell with orifices, deformation, internal forces.
