According to Caldarone (2009), as strength increases, the slope of both of portions of the stress-strain diagram
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.
1-LY11/6/350 strain gauges (SG) were used (see Figure 2) to measure the strain, which was recalculated into stress using the true stress-strain diagram
obtained from the coupon tests.
To understand the annealed state of copper, a full comprehension of its stress-strain diagram
The strength of thermal-insulating materials under compression should be assessed considering the specifics of deformations development, which manifests itself best in the stress-strain diagram
(Vaitkus et al.
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.
2b) initiation of damage also corresponds to the transition from the initial linear part of the stress-strain diagram
to the non-linear behaviour.
Figure 1a provides the stress-strain diagram
experimentally obtained from a wire with a diameter of 1 mm.
To account for the non-linearity of stress-strain relationship in the calculation of measured flexural strength, he replaced the curvilinear tensile stress-strain diagram
by a simple rectangular stress diagram with the same dimensional constraints proposed by Whitney.
A tensilgram in engineering language is a stress-strain diagram
and the area under the curve is the thermodynamic equivalent of work (figure 1).
c) From the stress-strain diagram
of the steel, it is possible to determine the stresses acting on the compressed ([[sigma].
