عنوان مقاله [English]
Today, the technical and engineering applications of textiles have received much attention from engineering researchers. It can be said that the most attention in this area is focused on medical textiles. There is a special group of medical textiles called compression garments, the function of which is to apply pressure to the body and was used for the first time for Pressure Therapy. The most important applications of these garments are to treat burns and varicose veins. The principle of treatment in these garments is the amount and distribution of pressure on the body, which is determined by the physician. The dimensions and material of the pressure garments should be chosen in such a way that the desired pressure is applied to the patient's body. For this purpose, one of the best methods for predicting pressure is to use simulation using finite element methods. In this research, a three-dimensional model of contact and pressure between the pressure garment and the human body is presented using ABAQUS software. Initially, the model was designed as a cylinder and the values of pressure, strain and stress on the hand and the pressure garment as well as pressure distribution showed that the model was properly designed and implemented in software. Then, the modeling was performed conically using real body sizes and pressure garment and the results were compared with the experimental results. Comparison of experimental results and model results showed that this model well simulates the pressure distribution and contact between the hand and the pressure garment. The method used in this research is a simple and practical method for model validation.
