摘要：

A fixture was designed to analyze the intra-ply shear properties of these fabrics. The nonlinear behavior of shear force versus shear angle and the deformation mechanism were analyzed. The curves for shear force versus shear angle and position of buckling for intra-ply shear test are recorded. Load-displacement curves of infra-ply shear tests are also analyzed. In addition to this, a program was developed in MATLAB using Hough transform to analyze the shear angle in the real-time image taken during displacement of specimen at various positions. These findings are important requirement for the further improvements in designing of picture frame fixture and to study the in-plane shear properties of 3D fabrics.
