 Full text | Abstract: During the first stage of our considerations, a model of the compression process of a 3D distance knitted fabric was related to a single connector fastened to it by articulated joints, and considered as a slender rod with an assumed shape. In our physical and mathematical models, the compression of a slender, elastic rod was based on assumptions concerning the knitted fabric’s morphology, as well as the mechanical properties of the threads, particularly monofilaments placed in the internal layer of the fabric. A calculation method was developed which enables to determine the functional dependencies between the compressing force and bending deflection, as well as a method of determining curves representingt he shape of the compressed rod – connector. A computer simulation of the compressed rod connecting the two outside layers of the knitted fabric, considering the variable parameters of the model, was carried out with the use of calculation algorithms elaborated by us, and MathCad program. |
