LARGE-SCALE EXTENSION AND RECOVERY OF PLAIN WOVEN FABRICS .1. THEORETICAL

This paper describes an attempt at a theoretical study of large-scale tensile deformation of plain woven fabrics. The basis of the investigation is to use a more realistic approximation of nonlinear yarn bending behavior for both the undeformed fabric state and the stress analysis than has been used by most previous workers. A theoretical model is proposed for the load-extension behavior of plain woven fabric during the first cycle of loading and unloading. In order to demonstrate the possibility of extending this to include cyclic behavior, a theoretical analysis of load-extension behavior over several cycles of loading and unloading is developed.
