“…Since the material is regarded as elastic, second Piola-Kirchhoff stress and Green-Lagrange strain are used, and data from the Kawabata's mechanical tester are simplified so as to be adapted to the stressstrain model [20]. As for implementation, FDEM is adopted [21]. To calculate energy minimization, an original descent method is used [9].…”

Gives an overview of the technique of current garment simulation and of the problems for more advanced simulation. To simulate the behaviour of a garment, three important models are usually used. They are: a garment model, a human body and an environment model. The models and the interaction among them are discussed using the conceptual‐mathematical‐posed problem structure of a model proposed by Barzel (1992).

Draping, or garment pattern unfolding process, is a 3-D to 2-D surface unfolding problem. In practice, although the pattern designers are aware of the distortion, they do not have any systematic method to calculate the distortion and they do not know how such distortion relates to curvature or other properties. In this article, the mathematical model of Draping, Stereographic Draping (SD), is used to derive the distortion property. In this method, two selected reference points, r 0 and r 1 , on the surface are mapped to p 0 and p 1 on the plane according to their distance apart. Then the position of a point, s, on a 3-D garment surface is mapped to the corresponding image, q, on the 2-D flat pattern based on the calculation of the distance of s with respect to r 0 and r 1 . It is equivalent to finding the solution of intersection of two circles. In general, such technique involves distortion, because the different garment surfaces have different intrinsic properties, and may not be isometric, or preserve distance. Although fabric properties can affect the fitting of fabric to the mannequin, when the fabric is rigid, such as paper or non-woven fabric, the Draping process is assumed to be unaffected by fabric properties. The scope of the problem can be confined to the geometric analysis. In this article, the theoretical analysis provides the distortion properties of distance and area with the condition when direct measurement and positioning from the developable garment surface can be accurately transferred to the flat pattern.

“…The finite element method (FEM) is a popular technique to analyse deformation of an elastic continuum, and has been introduced into cloth modelling (Collier et al, 1991;Eischen et al, 1996). Imaoka et al (1989; used FEM to predict 3-D drape shape of a skirt from its 2-D paper pattern. Although FEM gives a clear mathematical description of elastic objects, it is insufficient to describe complex boundary conditions in cloth simulation.…”

Drape is a characteristic behaviour of flexible cloth, so it is important in modelling cloth. The paper introduces a novel method to model drape using a few shape parameters, predicted according to the pattern structure and mechanical properties of cloth. The technique is used to visualize the 3-D drapeability of cloth and is then extended to simulation of a skirt. The general shape of a flared skirt of large deformation is predicted based on several shape parameters. Moreover, the constructed skirt model is used as pre-draped initial shape for the popular physically-based model ± particle system. Kawabata Evaluation System (KES) plots of cloth are applied for accurate mechanical calculation. The simulated results show good agreement with actual cloth materials.
