“…Limited extensibility in fiber direction will have a pronounced effect on the overall deformation, resulting in dominant shear behavior and local thickening rather than thinning. The fiber directions may be tracked intuitively using drawn lines [6], a tracer in the fabric [7,8] or directly from the materials' inherent pattern [9,10]. However, full field strain measurements, using photogrammetry for example, provide a more complete picture of the local deformations.…”
