A method for the evaluation of the draped figure of the isotropic sheets at an arbitrary degree of draping under the same conditions as in the F.R.L. drape test was examined by using the similarity rule.
It was confirmed that π (=L/ (EI/w) 1/3) shows the degree of draping of sheets as the drape coefficient. π5 obtained from the relationship between the own-weight and elastic resistant force was expressed by π5= (w/E) 2/3⋅π, and it was confirmed that the draped figure at a fixed it can be evaluated by using (w/E) 2/3.
It was proposed that a method for the evaluation of the draped figure of isotropic sheets could evaluate the draped figure by using the draping index π and draped figure index (w/E) 2/3.
