  • Evaluation of rheological properties of a thread using numerical methods
    Geršak, Jelka
    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 ▫$\sigma$▫(▫$\epsilon$▫) curve. The stress-deformation ▫$\sigma$▫(▫$\epsilon$▫) 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 conscruction of the average ▫$\sigma$▫(▫$\epsilon$▫) curve
