Abstract
Many kinds of pressure garments are currently used for various applications, such as treating of hypertrophic scars, reversing the effect of shock on the body's blood distribution, improving energy saving for athletes and enhancing the aesthetic appearance of the wearer. In order to design the desired pressure garments, predicting the amount of pressure is mandatory. Although many researchers have used the Laplace law as the prediction equation, there has been some discrepancy between predicted and experimental measured pressures. In this study, we focused on one of the parameters which influence this discrepancy. To predict the pressure by this law, the induced tension in the material is measured by a tensile strength device, and then is inserted into the equation while the real tension is induced by extending on curvature shape. We measured the tension induced in the rubber band, which was extended on a cylindrical surface by using a new tensile test assembly. Subsequently, this tension was compared with the tension induced in the flat geometry which is commonly used. The results show that there is a significant difference between the tension in the curvature and flat geometry.
