multiscale constitutive modeling and numerical simulation of Fabric Material
International Journal of Solids and Structures, 2006Co-Authors: Ben Nadler, Panayiotis Papadopoulos, David J SteigmannAbstract:A multiscale model for a Fabric Material is introduced. The model is based on the assumption that on the macroscale the Fabric behaves as a continuum membrane, while on the microscale the properties of the microstructure are accounted for by a constitutive law derived by modeling a pair of overlapping crimped yarns as extensible elasticae. A two-scale finite element method is devised to solve selected boundary-value problems.

Numerical simulation of knitted Fabric Material with multi-scale finite element method
2009 International Conference on Machine Learning and Cybernetics, 2009Co-Authors: Cui-yu Li, Xiao-tao ZhangAbstract:Due to complexity of micro-structure of knitted Fabric, there is little related work reported in literatures. With the aid of the micro-mechanical model of knitted Fabric which characterizes the special properties of knitted Fabric, the draping and buckling of a square knitted Fabric sheet putting on a circular desk are successfully simulated by Multi-scale finite element methods (MsFEM) and traditional finite element method. The knitted Fabric sheet is discretized with 8-nodes shell elements, which are designed for finite deformation and suffice to describe the large rotation of knitted Fabric sheet during draping. For the sake of simplicity, the nodes of the knitted Fabric sheet on the edge of the desk are assumed to fix. The simulation results of MsFEM are compared with the experimental ones, and in good agreement with the observations. The result demonstrates that the advantages of the multi-scale finite element method for numerical simulation of knitted Fabric Material, i.e. significantly reducing computational efforts, and improving the accuracy of the solutions.

Numerical simulation of woven Fabric Material based on multi-scale finite element method
2008 International Conference on Machine Learning and Cybernetics, 2008Co-Authors: Cui-yu Li, Xiao-tao ZhangAbstract:The multi-scale finite element method (MsFEM) and a multi-scale model for Fabric Material are introduced. MsFEM methods can capture the effect of small scales on the large scales without resolving all the small scale features. The model is based on the assumption that, at the continuum level, Fabric behaves as a finitely deformable membrane. Moreover, the Fabric is assumed to be composed of two families of continuously distributed yarns constrained at all time to occupy a common evolving surface in three dimensional spaces. Draping and buckling of woven Fabric are simulated with multi-scale finite element method. The simulated results are in good agreement with the experimental observations. The results show that precision of the draping and buckling simulation is improved evidently because of the multi-scale model. The investigation sets up the theory and technique basis for the fitting system in the dress CAD.
