TLDR
In this article, a shear flexible shell theory is used to predict the drape of fabrics, where the material characteristics used in the model are Young's modulus in the warp and weft directions, shear modulus, and Poisson's ratio.Abstract:
A shear flexible shell theory is used to predict the drape of fabrics. The fabric is considered a continuous, orthotropic medium. Finite element formulations are used to numerically solve governing equations under specific boundary conditions. Initially, the fabric is assumed to be a flat plate, which goes through large deformation during the process of draping. The load (fabric weight) is applied in steps to the model. During each step, a Newton-Raphson iteration method is used to solve nonlinear equilibrium equations under current load level. The material characteristics used in the model are Young's modulus in the warp and weft directions, shear modulus, and Poisson's ratio. Simulation of a 30 × 30 cm fabric draped over a 12 × 12 cm table is achieved in less than eight minutes of CPU time on an IBM RS 6000 workstation.read more

On a stress resultant geometrically exact shell model. Part IV: variable thickness shells with through-the-thickness stretching
TL;DR: In this paper, an extension of the shell theory and numerical analysis presented in Part I, II and III to include finite thickness stretch and initial variable thickness is presented, which plays a significant role in problems involving finite membrane strains, contact, concentrated surface loads and delamination (in composite shells).

The synthesis of cloth objects
TL;DR: A method for modelling cloth material hanging in three dimensions when supported by any number of constraint points is described and the cloth synthesized with this model contains folds and appears more realistic than simple texture mapping.

Dressing animated synthetic actors with complex deformable clothes
TL;DR: The paper describes the physical models used and then addresses several problems encountered and describes a new approach to the problem of handling collisions among the cloth elements themselves, or between a cloth element and a rigid object like the human body.
