Numerical Analysis of Peirce's Cantilever Test for the Bending Rigidity of Textiles

This paper deals with the numerical analysis of a test for the bending rigidity of textiles as proposed by Peirce. The mathematical model treats textile product as an elastica which is subject to large deflections. The results of the numerical calculations discussed in this paper are presented on the relevant graphs. The optimal conditions of Peirce’s test were also considered, in order to obtain the results of measurements most sensitive to changes of the input parameters. The results of the calculations are compared with the practical implementation of this test as commonly applied in textile laboratories.
