Abstract

Knitted fabrics are considered hyperelastic materials due to their high deformation at very low forces. Their mechanical behaviour is atypical and requires extensive theoretical and experimental studies. There are a number of models treating the mechanical behaviour of knitted fabrics, but they are limited in applicability mainly due to structure restriction and simplifying hypothesis. The paper approaches the analysis of tensile deformations of knitted fabrics from a new angle, based on the analysis in real time using advanced optical systems. The paper presents the working method and comments on the results..
