This paper investigates the high cycle tensile fatigue behavior of steel rebar reinforced − UHPFRC elements, at a fatigue load ratio, i.e., R-ratio of 0.3, representative for structural applications. Prior to testing, magnetoscopy is conducted on each spec ...
High-performance concretes are increasingly employed in various civil engineering applications due to their exceptional short- and long-term performance. As a result, there is a significant need for simplified numerical simulation methods to effectively in ...
Neutron embrittlement of in -core and out-of-core components made of ferritic steels is one of the key parameters limiting the life of power plants. Owing to the small volume of available irradiation facilities and the limited number of neutron-irradiated ...
In this paper, we describe a numerical framework for achieving passive thermal cloaking of arbitrary shapes in both static and transient regimes. The design strategy is cast as the solution of an optimal control problem (OCP) for the heat equation where th ...
Ion migration is an important phenomenon affecting the performance of hybrid perovskite solar cells. It is particularly challenging, however, to disentangle the contribution of H+ diffusion from that of other ions, and the atomic-scale mechanism remains un ...
The design rules for the verification of civil engineering steel structures against fatigue are compiled in the European harmonized design standard Eurocode EN 1993-1-9 released in 2005. This design standard is currently under revision, together with all o ...
