The methods developed in Chap.  9 are applied and validated in a static T-pose breast-bra interaction model. A customised human model of a female test subject with a deformable breast and skin is created. Four different bras are modelled and combined with the human model using a novel dressing method. Validation is performed through cross-sectional comparison, fit analysis, and pressure analysis. The first two validation steps utilise 4D scan data and BodyTex4D. The results show a high usability of the digital models, allowing differences between the four bra designs to be identified based on pattern and seam construction. The digital pressure analysis proves to be particularly advantageous compared to experimental methods. Overall, 4D scan data and BodyTex4D enhance the validation of FEM models, leading to improved accuracy in digital simulations.

摘要

The methods developed in Chap.  9 are applied and validated in a static T-pose breast-bra interaction model. A customised human model of a female test subject with a deformable breast and skin is created. Four different bras are modelled and combined with the human model using a novel dressing method. Validation is performed through cross-sectional comparison, fit analysis, and pressure analysis. The first two validation steps utilise 4D scan data and BodyTex4D. The results show a high usability of the digital models, allowing differences between the four bra designs to be identified based on pattern and seam construction. The digital pressure analysis proves to be particularly advantageous compared to experimental methods. Overall, 4D scan data and BodyTex4D enhance the validation of FEM models, leading to improved accuracy in digital simulations.
