| Abstract | |
The mechanical behaviour of textile materials, fundamental to textile composites, is critical for designing advanced material solutions. Mechanical modelling of textiles is highly complex due to the interactions between yarns, resulting in distinct nonlinear characteristics for different textile patterns. Therefore, engineering methods are essential for analysing loading scenarios and integrating decisions about textile patterns, their alignment, and other factors into the design process. One potential approach is the use of multiscale analysis. We present a novel approach for multiscale modelling in this context. Our approach models the mesoscale using beam elements and enhanced contact models to capture the interactions between yarns, while the macroscale employs solid elements with material non-linearity. This developed approach is verified by comparing pure mesoscale and multiscale results using uniaxial, biaxial, and picture frame tests. Additionally, the applicability of the multiscale method is demonstrated under more complex loading conditions. This proposal aims to model the overall mechanical response of textile patterns under complex loading conditions and can be used as a tool to evaluate the mechanical behaviour of textiles comprehensively.
