A simplified model of textile fabric drape based on two-dimensional ri
ng theory is applied to the circular geometry of the drapemeter. A mat
erial parameter incorporating fabric properties and drape geometry is
identified and used to characterize the drape response in terms of the
energy contained in a series of deformed rings. Results of the analys
is include the prediction of drape configurations and an explanation o
f their nonuniqueness based on energy content.
