Description
Summary:Based on two basic assumptions: the Poisson's ratios ν x , ν y are constants; and tensile rigidities Ex , Ey are nonlinear functions of the stress, a new nonlinear theoretical model to describe the tensile behavior of fabrics based on the orthotropic theory is presented here. This new model was used to predict the uniaxial tensile properties of fabrics from the strip biaxial test by the Poisson's ratios ν x , ν y calculated from the strip biaxial experimental results. The uniaxial tensile experiments for plain knitted fabrics and for plain woven fabrics were carried out and the experimental results showed good agreement with the results predicted by the new model. It is the first time the relationship between the uniaxial tensile test and the strip biaxial tensile test has been established. The paper provides a simple and effective method for comparing the results obtained by different experimental methods.
