Crack-controlled parameters, such as shape factor, characteristic length, and orientation parameter, are found to be significant factors governing strain behavior.
The investigation considered various parametric factors, including crack geometry, support, and loading direction.
The results revealed distinct strain distributions with variations attributed to different factors.
The straight crack demonstrates sensitivity to load transfer through the crack, affecting strain generation at crack tip C2 even being distant from the excitation source.

Here, the different behaviors are only due to the differences in material properties at elevated temperature (Fig. 1).
These results show that, even when the same sections are used, the fire performance of members in HSC is inherently worse than for members in NSC, due to a more severe degradation of the mechanical properties at elevated temperature.
At the material level, HSC experiences a reduction of material properties with temperature that is more severe than for NSC.
These effects add to the differences in mechanical properties, all of which contribute to make the HSC columns more vulnerable to fire than NSC columns.

Environmentally-assisted material degradation involves mass transport and mechanical processes interacting in the material.
The numerical modeling of a showcase demonstrates a crack initiation as well as a crack propagation situation with respect to the determination of stress-intensity factors; a crack deviation situation with a curvilinear crack path is modeled by the introduction of a geometrical perturbation and a locally enhanced species concentration.
A mass transport model describes the evolution of a time dependent concentration field that affects the mechanical properties.
The strain energy density ψ is as- sembled by two factors, ψ=1-ω2+kψ0εij, whereupon ψ0εij= 12λεkkεll+ μεijεij with Lame´-constants λ and µ.
The material degradation is modeled by the factor 1-ω2+k, where ω=1 defines a fully degradated material.

Effect of Thermal Aging at Low Temperature on the Mechanical Properties and Corrosion Resistance of LDX 2404 Duplex Stainless Steel R.
It is well known that when duplex stainless steels (DSS) are subjected to temperatures ranging from 300 to 1000 °C they may undergo precipitation of several phases, which can seriously impair their mechanical properties and corrosion resistance.
The present work studied the effect of thermal aging (up to 2000 h) at 475 °C on the corrosion and mechanical properties of the newly developed 2404 DSS.
Their broad applicability is due to their combination of excellent mechanical properties and high corrosion resistance.
The precipitation of these tertiary phases can severely impair the mechanical properties and corrosion resistance of DSS [1-5].
