    Numerical simulation and experimental study of trapezoidal tear of triaxial woven fabric
    (Wydawnictwo Politechniki Łódzkiej, 2022) Zhou, Hongtao; Jiang, Weijing; Bin, Zhou
    The tear damage of triaxial woven fabric (TWF) are investigated by numerical simulation method and experiment method to study the tear properties of samples with pre-cut in different directions. It is analysed that the changing law of tear load and the characteristics of tear failure during tear process. The results indicate that the tear load-displacement curve can be divided into low modulus region, high modulus region and shock region, which are related to initial stage, pre-cut opening stage and tear opening expansion stage the tear process of TWF. When the pre-cut is parallel to the yarn, samples have higher tear load and larger tear starting position.
