The recrystallization assisted microstructural changes during cyclic heat exposure are surmised detrimental to the thermal fatigue resistance of tungsten monoblocks that cover surface divertor components a nuclear fusion reactor. A numerical framework predict in is presented this work. based on model coupled Johnson-Mehl-Avrami-Kolomogorov (JMAK) type model. influence initial (starting) state, ...

Abstract Feuerverzinkte Stahlbauten haben sich im Hochbau etabliert und gehören zum Stand der Technik. Sie erreichen Korrosionsschutzdauern in Größenordnung Lebensdauer des Bauwerks (≥100 Jahre). Die Anwendung dieses Korrosionsschutzsystems hätte auch Brückenbau ein großes Potenzial. Wirtschaftlichkeit Nachhaltigkeit sind neben den Neubaukosten insbesondere von während anfallenden Unterhaltungs...

Introduction Fatigue is the structural damage that leads the components of a wind turbine to sudden brittle failure when it suffers cyclic loading [15]. As the size of wind turbines is growing, fatigue loads become more and more significant for the design of major structural components. Concerning fatigue in a wind turbine tower, the fore-aft tower foot bending moment is considered as the most ...

This research work has addressed demand side flexibility in a smart grid oriented building. The principal purpose has been to build a short term forecasting model that will predict the next hour consumption. Three advanced methods of forecasting have been investigated for this purpose, the ARIMA (Autoregressive Integrated Moving Average) model, Artificial Neural Networks (ANN) and Support Vecto...

Abstract An integrated energy system’s load consists of diverse forms, including electric load, cooling heat and more. Due to its strong randomness volatility, traditional forecasting methods are not suitable for the system. To address issue short-term multiple loads system, proposed paper utilizes generating adversarial networks (GAN). The method analyzes characteristics comprehensive multi-lo...

Fixed-bottom foundations of offshore structures, mainly monopiles, are subject to extreme events and other critical cyclic nature loads. Since wind turbine structures slender, the manufacturers turbines give a range frequencies for safe operation during structure’s life cycle. Highly reliable measurements accurate determination shear moduli damping ratios crucial ensure stability these example,...

In this research, softening and ratcheting behaviors of Ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. Experimental tests were performed by a servo-hydraulic INSTRON 8802 machine. The mechanical properties of specimens were determined according to ASTM E8...
