Abstract: In this paper, finite element method (FEM) software is used to simulate the large deformation process of pole during the pole vaulting. The deformation, jump heights and performance index are obtained from the calculations for poles made of different materials. The highest records are predicted for different materials' poles through the design of pole sections. Carbon fiber reinforced composites poles with uniform and varying sections are designed for Bubka as an standard, to let him to reach higher height.
