Large deflection analysis of bending was performed by the finite element method using curved beam elements. The calculation was performed on the basis of the infinitesimally small strain theory and the non linearity due to the change in the loading direction during large deformation was considered. As a result, the deviation from the linear bending deflection appeared. Simultaneously, the deflection of a ski of conventional type with a curving shape was measured by three-point bending where the load was limited within the range of normal use; i.e. the static load applied in the bending was less than 700N, which subjected the curvature of not less than 1.4m. Since the load-deflection relationship obtained was almost exactly linear, no geometrical nonlinearity was found in the bending under the present condition.
