A textile fabric is a highly nonlinear mechanical system and defies analytical solution methods regarding large deformation problems. In this research, fabric parts are modeled as flexible, doubly curved shells that can accommodate stretching, bending, and transverse shear deformations. Shell theory based on large displacements and rotations is used to formulate a finite element solution strategy. Orthotropic fabric sheets are treated in the formulation. The formulation includes an efficient global nonlinear static algorithm to cope with contact and buckling problems.
