Recently a new type ski which is called the "wide width ski" is available on the market. Since the ski has a wide width and a short length, the radius of curvature of the side cut is smaller than that of the ski used up until nOW. It has been explained that the side cut of the ski is very important for a ski turn. Therefore, it is of great interest as to why such a ski with a different side cut has been developed and what kinds of effect the different side cut gives on the ski turn. The authors have already developed a numerical approach for estimating the ski turn caused by a skier's edging action. Since the dynamic bending deformation and movement of the ski can be analyzed by the approach, we can estimate the effects of the shape and mechanical properties of the ski on the ski turn by using the approach. In the present study, the ski turn of four kinds of ski with a different width, length and flexural rigidities are estimated numerically. The effects of the ski's flexural rigidities, width, and length on the locus of the ski turn and the relative direction of the ski to the tangent of the locus are discussed from the numerical results.
