Abstract: Two cobalt-based superalloys containing 1.6% and 2% carbon respectively were studied, with the emphasis on the influence of the carbon content on their microstructures, wear resistance, and ...

Abstract: A can type combustor with a rotating casing for an innovative micro gas turbine has been modeled, and the combustion characteristics were investigated. The simulations were performed using ...

Abstract: The chemical composition of Stellite® 21 alloy was modified by doubling the molybdenum (Mo) content for enhanced corrosion and wear resistance. The specimens were fabricated using a casting ...

Abstract: A formulation based on the linearized shallow shell theory has been developed by Delale and Erdogan to determine the stress intensity factors of a shell with a through-the-thickness crack. The drawback in the formulation ...

Abstract: The steel stiffened segment in a steel–concrete connection joint is critical to the load capability of the cable-stayed bridge with hybrid girders. The research focused on the improvement of steel stiffened segments by ...

Abstract: To investigate the mechanism for the enhanced load-bearing capacity of stud connectors owing to an increase in concrete strength, the push-out test is analyzed using nonlinear finite-element (FE) models. A distinct failure ...

Abstract: This study investigates the acoustic emission (AE) and physicomechanical properties of concrete under three sulfate attack conditions: continuous immersion, wetting–drying cycles, and cyclic loading coupled with wetting–drying ...

Abstract: Using UDEC discrete-element method (DEM) and field monitoring method, the influence rules of slope height, slope angle, and excavation stage on the stress field, displacement field, and stability safety factor of high steep ...

Abstract: Tensions in the hangers of suspension bridges are vital for quality control during their construction and health monitoring and maintenance during service. Hence, accurate and efficient estimation of the tensions in hangers ...
