Abstract
This paper presents a computational model that simulates the deformation of materials in shoe uppers and that quantifies the distribution of forces on the foot surface in a complete step. A preliminary linear elastic model based on the finite element method was developed for the upper, using a simple triangular element of three nodes. This model can be used for different feet of the same size, for sizes of the same design, and for materials with different elastic parameters. The aim of this model is to provide functional and aesthetic valuation in CAD (computer assisted design) footwear design. The application achieved will be the first tool to provide footwear manufacturers with the capacity to value the functional features of a design virtually, without having to make prototypes or use footwearers. This application will minimize the time and the costs that a new shoe collection generates.
