| Abstract: | In this paper, adifferential equation of equilibrium for Leipholz bar with a large deflection is derived, and the quasi-variational principle that is consistent with the differential equation of equilibrium is given. Using the quasi-variational principle, the load-deflection expression of the Leipholz bar with simply supported at its ends is obtained. |
