Ski and Snowboard Stiffness Calculator

This tool models the bending stiffness and deflection of a ski design based on your chosen geometry, core profile, and composite layup. By combining your shape dimensions with material properties, it calculates the EI profile (bending stiffness) along the running length, simulates deflection under load, and visualizes the results in easy-to-read graphs. It’s designed to help ski builders fine-tune performance before committing to a build.
