Finally, the results of identification in the following chapters
will be presented as x sx.
The transformation of the data obtained from the strength machine
(curves displacement-force) to curves strain e– stress r (kN/
m) is required. Results obtained from the uniaxial tensile tests
(three specimens for warp and three specimens for weft have been
examined) are presented in Fig. 3. It is worth pointing out that
curves have a very repeatable characteristic and shape; therefore
it is difficult to distinguish each of them in Fig. 3.
