BENDING PROPERTIES OF LAMINATED CLOTHES WITH SEAM IN THE DIRECTION OF WIDTH

Abstract

In order to clarify the bending properties of the laminated clothes having regularly different bending rigidities, such as the padded clothes or the quilting coats, a non-uniform beam model whose bending rigidity is variant along the direction of the length is supposed. On the basis of the model an analytical method on the bending behaviour is considered.
It was proved that the analytical method using “Area-moment method” was effective for describing the bending of the laminated clothes with the ease in calculating with a micro computer.
By this method, if the distribution of bending rigidity and weight in a laminated cloth is previously known, it is possible to obtain the correct deflection curve.
Furthermore, referring to the deflection curve of the laminated cloth, the partially unknown bending rigidity can be calculated.
