Abstract :A finite element analysis method for snow deformation problems is presented. Since the snow possesses the incompressibility under the positive pressure, then the penalized mixed form is used in the finite element discretization. Furthermore the large snow deformation dominated by viscous behavior may cause complex free-surface motion such as the fusion and fission. In order to capture these phenomena, the VOF method is employed. The motion of snow is thus reduced to the convection equation of VOF function which is defined by a volume fraction of snow in each mesh. The evolution process of VOF function is calculated by means of the CIP method. The essential boundary condition in which displacement is prescribed is incorporated in the solving equation using a penalty method. It allows us to locate the boundaries in the analysis domain irrespective of the finite element mesh. The developed method is applied to several examples and the validity of the method is proved.
