Abstract: The paper proposes a new method for estimating the ultimate non-destructive load and deformation values during stretching of elementary synthetic yarns, based not on critical breaking values, but on a statistical analysis of the breaking load and deformation values determined experimentally. The described method for estimating “safe” ranges of loads and deformations under mechanical impacts, using the three-parameter Weibull distribution, can be extended to a wide range of materials.

Keywords: synthetic yarns, non-destructive loads, non-destructive deformations, Weibull–Gnedenko distribution, three-parameter Weibull distribution.
