The goal of this project is to develop a computational modelling platform based on advanced multi-physics finite element techniques to unravel some key aspects of the tribophysics of shaving. Particular focus is placed on developing models predicting the flow and spread of the shave prep under the cartridge guard during a shaving stroke. This work is developed in parallel with other projects conducted in Ìì·¢ÓéÀÖÆåÅÆ_Ìì·¢ÓéÀÖAPP-¹ÙÍø|ÏÂÔØ which aims to establish statistical models linking consumer perception (the so-called ¡°glide comfort¡±) to physical attributes of razor and shave preparation. An important side aspect of the modelling work is to experimentally characterise the rheology of shave preparation in order to implement appropriate constitutive models in the finite element environment.
