Abstract: Based on a state variable theory proposed by Onat some discriminating creep tests of stainless steel have been designed and carried out at elevated temperature conditions. Quantitative correlations ...

Abstract: Transient temperature and stress distributions are analytically and experimentally investigated for a butt welded plate of HT36-steel. A two-dimensional thermal FE-model is shown to represent the ...

Abstract: A hydrogen-induced fracture process in the HAZ of a QT-steel weldment is studied numerically. Two-dimensional models are used to estimate the transient distributions of stress and hydrogen during ...

Abstract: An analytical model for diffusion of hydrogen in presence of reversible and irreversible traps in the metal is given. A numerical model for solution of the resulting system of nonlinear partial ...

Abstract: Commercial IGCC power plants need gas turbines with high efficiency and high power output in order to reduce specific installation costs and fuel consumption. Therefore the well-proven 154 MW ...

Abstract: A method is developed for calculating the line load and the deflection curves for a pair of contacting rollers supported at the ends. The formulation includes the possibility of varying flexural ...

Abstract: A theoretical approach for calculating pyrite oxidation in acid sulfate soil with a macropore/matrix structure is described. This approach accounts for vertical oxygen transport through soil macropores and the subsequent ...
