On-Line Measurement of Fabric Bending Behavior: Part I: Theoretical Study of Static Fabric Loops

In order to develop an on-line system to characterize fabric bending rigidity, four potential loop shapes are proposed. Loop shapes are chosen such that they can be formed under dynamic conditions. Results from theoretical models of these loops show the nature of the response of loop shapes to varying fabric bending behaviors. Two candidate loop shapes are identified for further investigation under nonlinear and dynamic conditions.
