Investigation on rheological properties of technical fabric 'Panama'

摘要

The paper presents the results of experiments on the technical fabric Panama carried out with the purpose of identification of inelastic properties of the warp and weft as well as the identification techniques based on the least-squares method. The material parameters are calculated on the basis of the uniaxial tension test in the warp and weft directions. The dense net type of a finite element is proposed to express the behaviour of the technical fabric in the FEM analysis. The Bodner-Partom and Chaboche viscoplastic models are applied to the description of the warp and weft properties. The results are verified by numerical simulation of the laboratory tests.
