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.enDla wszystkich w zakresie dozwolonego użytkuFair use conditiontriaxial woven fabrictrapezoidal teartear strengthfinite element analysistkanina trójosiowarozdarcie trapezowewytrzymałość na rozdarcieanaliza elementów skończonychartykuł - konferencjaLicencja PŁLUT License10.34658/9788366741751.48
