Finite element modelling of textile-soft material interaction using 3D/4D scan data

The interaction between textile and soft material occurs in different areas. It can be found in the clothing, medicine or automotive sector. In this paper the textile-soft material interaction has been investigated using the example of the breast-bra interaction. 4D scan data of a test person dressed with a bra and unclothed were acquired in two scan poses. The scans were analysed by cross section comparisons. A finite element model was developed from these scans. Three different meshing methods were modelled. A FEM model of a bra compressing the female breast was successfully developed. The breast deformation is modelled the best with a solid body model. In the validation comparison of the modelled breast deformation and the original breast deformation, a very good agreement can be seen.
