Exact solution for finite deformation problems of cantilever beam with variable section under the action of arbitrary transverse loads

This paper deals with finite deformation problems of cantilever beam with variable section under the action of arbitrary transverse loads. By the use of a method of variable replacement, the nonlinear differential equation with varied coefficient for the problem can be transformed into an equation with variable separable. The exact solution can be obtained by the integration method. Some examples are given in the paper, and the results of these examples show that this exact solution includes the existing solutions in references as special cases.
