Abstract : Foot pressure ulcers PU mainly result from excessive pressure intensity internal strains above 50% for about 10 minutes or prolonged compression internal strains above 20% for about two hours. It is therefore crucial to monitor the internal strains using biomechanical models combined with skin surface pressure measurements to improve daily examination. A biomechanical Finite Element foot model was elaborated to analyze the internal strains. A new criterion, defined as -cluster volume-, was introduced by considering the volume of the largest group of adjacent nodes exhibiting a Von Mises VM strain over the 20 and 50% thresholds.
