Abstract

Considers the complexity of a problem of thread’s rheological properties evaluation, and evaluates the visco‐elastic properties of a thread on the basis of static tests using numerical methods. Describes a new software package VILKUS which was designed and programmed for this purpose. This program calculates parameters needed for the evaluation of visco‐elastic properties on the basis of numerical values of a stress‐deformation σ(ε) curve. The stress‐deformation σ(ε) curve served as a starting‐point for evaluation of visco‐elastic properties of threads. The B‐spline approximation using the least squares method was chosen as an appropriate and suitably smooth curve for construction of the average σ(ε) curve.
