In general, it is widely accepted that the specimens are not damaged before the peak point of the stress-strain diagram
. During the relaxation experiment, when the constant level of input strain varied from low to high, the property of the asphalt mixture changed from linear viscoelasticity to viscoplasticity .

For this calculation, the yield strength of the tube material is determined from the stress-strain diagram
of C12200 copper with an expansion ratio of 4% used for the strain value which provides the yield strength of 16,500 psi (114 Mpa).
One example is the change in the deformation limits above 50 MPa, altering the stress-strain diagram
. For conventional concretes is common to adopt the specified strain of shortening of concrete at the beginning of plastic level ([[epsilon].sub.c2]) is 2 per thousand and the specified strain of shortening of rupture ([[epsilon].sub.cu]) is 3.5 per thousand.
Therefore, we should look for a universal function, not for a specific stress-strain diagram
and phase diagram of a concrete or a reinforced concrete element M-(1/r), which can be represented by irregular fractional-rational functions (5) or (7), since they allow us to describe the stress-strain state of a bent and centrally or eccentrically compressed or tensed concrete or a reinforced concrete element.

The stress-strain diagram
with limited descending branch of the concrete (Typ, [TEXT NOT REPRODUCIBLE IN ASCII] 2003) and bilinear stress-strain relation for the bar reinforcement were used (Fig.
ACI Committee 363-1992  reported that as the concrete strength increases for HSC, the post peak portion of the stress-strain diagram
almost vanishes or descents steeply.
2a) the damage initiation does not affect the slope of the stress-strain diagram
, as the resistance to the deformation in fibre direction is provided by the corresponding fibre system (inlay 0[degree] yarns).
