Large deflections and stability of spring-hinged cantilever beam

Milan Batista

Vol. 14 (2019), No. 2, 295–308
Abstract

We investigate the influence of spring stiffness on large deflections and the stability of a spring-hinged cantilever subjected to a conservative tip force. Using the closed-form solution of the equilibrium equation and the Jacobi accessory equation, we determine the beam equilibrium forms and their stability. The solution for a spring-hinged cantilever beam subjected to a follower force is provided. The results are presented in graphical and tabular forms.
