A corotational interpolatory model for fabric drape simulation

Abstract

SUMMARYFabric drapes are typical large displacement, large rotation but small strain problems. In particle models for fabric drape simulation, the fabric deformation is characterized by the displacements of the particles distributed over the fabric. In this paper, a new particle model based on the corotational concept is formulated. Under the small membrane strain assumption, the bending energy can be approximated as a quadratic function of the particle displacements that are finite. In other words, the tangential bending stiffness matrix is a constant and only the tangential membrane stiffness matrix needs to be updated after each iteration or step. On the other hand, the requirement on the particle alignment is relaxed by interpolating the particle displacement in a patch of nine particles. To account for the membrane energy, a simple and efficient method similar to the three-node membrane triangular element employing the Green strain measure is adopted. With the present model, the predicted drapes appear to be natural and match our daily perception. In particular, circular clothes and circular pedestal that can only be treated laboriously by most particle models can be conveniently considered.

A geometric nonlinear rotation‐free triangle and its application to drape simulation

“…It looks natural and is also consistent with the prediction in [26]. the Mooney coefficients˛1 D 180.88 kPa and˛2 D 18.088 kPa [32].…”

“…The predicted top and isometric views by using 31 120 nodes are portrayed in Figure 20. These predictions seem to be realistic although some other literatures, namely, [26], produce a four-fold pattern whereas the present one contains eight folds. Fabric draped over a circular pedestal has a multiple stable pattern nature.…”

“…The authors proposed several corotational models for cloth simulation [14][15][16][17]. In this paper, we use the modified bilinear solid-shell finite element model to compute the textile deformation [16].…”

“…Many models have been proposed to model cloth deformation [7][8][9][10][11][12][13][14][15][16][17]. These include geometric models, mass-spring models, finite element models, finite volume models, and grid-based models, among others.…”
