Abstract
In this study a 3D model of a yarn pure bending is introduced. The main focus of the study is on the realization of a 3D yarn geometrical model, incorporation of anisotropic material properties and validation of yarn finite element meso-model using experimental results. The material properties of yarn were assumed linear orthotropic. The required engineering constants were obtained from experimentally measured tensile, compression diagrams of a pp-glass yarn. The accuracy of the applied engineering constants was investigated by FE modeling of yarn pure bending.
Key Words: Yarn, finite element, meso modeling, bending, anisotropic material
