Experimental and numerical analyses of fabric off-axes tensile test

Tensile tests are applied on fabric in seven directions oriented with 15 degrees increment with respect to the warp direction. These tests are carried out with articulated jaws to ensure their homogeneity. In addition to measuring the stress and displacement fields, a strain optic analysis by videos acquisition and processing is implemented. An analysis of the anisotropy and degree of homogeneity of the strain fields is presented. A linear elastic orthotropic model is identified on a particular zone of the tensile curves. A numerical analysis by finite elements method has been carried out and compared with experimental results.
