Exact Static Analysis of In-Plane Curved Timoshenko Beams with Strong Nonlinear Boundary Conditions

الملخص EN

Analytical solutions have been developed for nonlinear boundary problems.

In this paper, the shifting function method is applied to develop the static deflection of in-plane curved Timoshenko beams with nonlinear boundary conditions.

Three coupled governing differential equations are derived via the Hamilton’s principle.

The mathematical modeling of the curved beam system can be decomposed into a complete sixth-order ordinary differential characteristic equation and the associated boundary conditions.

It is shown that the proposed method is valid and performs well for problems with strong nonlinearity.
