“…Another issue that is frequently raised relates to the imprint of the through thickness anisotropy to the surface temperature, which is of particular importance for a laminated structure. Melvin et al [39], concluded that the surface temperature differences are attributed to the whole laminate and not only to the top lamina of the examined multi-layered composite. In this case the thermal anisotropy as described in Eq.…”

“…[38]. In the case of brittle fibrous composites, this monotonic temperature increase can also be attributed to heat release due to the accumulating flaws in the structure which in the presence of irreversible processes may overcome the thermoelastic effect [39]. In the case of cyclic loading, the phenomenon of intense heat generation that precedes catastrophic failure is usually recorded at the final cycles of the fatigue life of the material.…”

“…They defined the yield strength as the corresponding stress for which the temperature tangent is horizontal (point B, Figure 1). Melvin et al studied in detail the heat generated during mono axial tensile test of steel [13,14]. They observed that the formation of micro cracks in the steel material can be defined by the loss of linearity of the temperature vs time (T-t.) diagram (point A, Figure 1).…”

In this paper thermal analysis was applied to determine the “Critical Stress” of concrete, different from its ultimate strength, able to produce the first damage in the structures under compressive loads. The Critical Stress can be thought as the stress able to produce the beginning of fatigue rupture within the material. Several specimens of high strength concrete were tested in order to define the incipient crack phenomena, also in internal part of the specimen not accessible by direct inspections, with the aid of infrared thermography. A finite element analysis completes the study and compares, for the same static loading conditions, the stress state with the experimental thermographic images. The final results show as the coupling of normal compressive test and the acquisition of the thermal images can be a useful aid to estimate a security stress value, indeed the Critical Stress, before the Ultimate Serviceability Limit (SLU) of the structure, defined as the maximum load condition before its failure.

“…The thermoelastic phenomenon has been recently studied by Caglioti et al They evaluate the temperature vs time for steel under monoaxial tensile test to estimate the yielding strength of the material as the zero derivative point of the temperature trend. Melvin et al studied the heat release during monoaxial tensile test of steel. They observed that the temperature has a linear trend in the first part of tensile test, but as the load increase, it changes its trend deviating from linearity.…”

Fatigue properties are of fundamental importance and extremely time consuming to be assessed. The aim of this research activity is to apply the Thermographic Method (TM) and the Static Thermographic Method (STM) during fatigue and tensile tests to correlate the temperature trend to the fatigue properties of an S355 steel. The material was retrieved from an in‐service port crane. Traditional fatigue tests were performed in order to evaluate the S‐N curve with a scatter band. Step load tests were carried out deriving the fatigue limit and the Energy Parameter of the material. Static tensile tests were performed to obtain the stress at which the temperature trend deviates from the thermoelastic behavior. The fatigue properties obtained by means of the energetic methods were compared to the traditional ones showing a good agreement.
