Measurement of Garment Pressure (Part 2)

Estimation of Pressure Brought on a Dome Surface by an Anisotropic Fabric

Abstract

In order to estimate the pressure brought on a body by deformation of a garment, two methods were adopted.
A fabric was deformed on a dome expansion apparatus. First, air pressure was measured. Second, pressure was calculated from strains and radii of curvature of the expanded fabric, using the equation (P = N₁ / R₁ + N₂ / R₂).
Two types of anisotropic materials were used for each method. Pressures obtained by the two methods coincided well with each other. As a result, it can be concluded that the results from the equation approximate to the pressures.
