    Abstract: The purpose of this study was to numerically investigate the influence of different snow conditions onto the structural behaviour of a snowboard undergoing the conditions of a carved turn. The properties of different types of snow were numerically idealized and the deformations and pressure distribution along the contact edge of a snowboard were observed, in an attempt to understand their sensitivity to the environmental parameters. A static load bench was developed in-house and a simplified snowboard prototype was manufactured in order to represent the in-situ conditions. The experimental set-up was idealized in a finite element model, representing the composite structure and its loading environment. A method for the validation of the numerical model was proposed, based on the comparison of the experimental and numerical displacement fields, and consisted in a best-fit algorithm to superimpose both deformed shapes. The congruence between the two deformed surfaces was expressed with statistical means, and constituted the target function for optimization frameworks. Additionally, the contact pressure at the interface was experimentally assessed with the use of pressure measurement tape, and compared with the numerical predictions. The results of the finite element simulation were then explored to give an insight on the influence of the snow properties onto the structural behaviour.
