placement of the loading plates was measured using an external laser displacement sensor. Therefore, no machine stiffness compensation is required. For this test, there are
established standards such as ASTM C 273 [AST94] and DIN 53292 [DIN292]. The test
details of the present study are summarized in Table 7.
b)
Figure 33 a) Experimental setup tensile tests; b) stress strain relationship of tested specimens
The test results in terms of macroscopic stress-strain relationship along with an image of
the test setup are given Figure 33. Analogous to the previous compression tests, the
stress and strain ware derived from the measured force-displacement curve. All tested
