That Is, show that an orthotropic material can have an apparent Young s modulus that either exceeds or is less than the Young s moduli in both principal material directions. In doing so, derive the conditions for which each type of behavior exists, i.e., derive the inequalities. Plot E E, for some contrived materials that exemplify these relations. [Pg.85]

Which is the same type of expression as was obtained for the transverse Young s modulus, 2- As with E2, the expression for G 2 can be normalized by a modulus related to the matrix, that is, [Pg.134]

Fink et al. [17] correlated measurements from different authors and test methods to compare Young s modulus for cellulose of type 1 and II. Most of the authors determined higher characteristic values for type I than for type II (Table 7). [Pg.792]
