Discussing Van Wyk's Theory[1] Concerning Compression of a Fibrous Mass

Abstract

Van Wyk's theory on the compression of a fibrous mass is refuted by the authors A is named "the modulus of the degree of packing."

A correction to van Wyk’s model of the compressibility of fibrous materials

“…Here, c ¼ bcosh þ dsinh and this expression of c has been pointed out earlier by Wakayama and Hattori. 8 A similar expression of c has also been derived for determining the fiber orientation in short fiber-reinforced composites. 9 Now, the mean value of c 2 can be again computed with the help of spatial averaging, i.e.,…”
