SIMULATION OF FABRIC DRAPE USING A THIN PLATE ELEMENT WITH FINITE ROTATION

The draping behavior of fabric is simulated by using four nodequadrilateral thin plate elements with finite rotation.The finite element formula-tion is based on the total Lagrangian approach.An exact representation of finiterotation is introduced. The strain energy function accounting for the material sym-metry is obtained by the tensor representation theory.To avoid shear locking,theassumed strain technique for transverse shear is adopted.The conjugate gradientmethod with a proposed line search algorithm is employed to minimize energy andreach the final shape of fabric.The draping behavior of a rectangular piece of fabricover a rectangular table is simulated.
