RISLife Assessment of Turbine Components Through Experimental and Numerical Investigations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new lifetime criterion for withdrawal of turbine components from service is developed in this paper based on finite element (FE) analysis and experimental results. Finite element analysis is used to determine stresses ...
Particle Swarm Optimization–Based Finite-Element Analyses and Designs of Shear Connector Distributions for Partial-Interaction Composite Beams
Publisher: American Society of Civil Engineers
Abstract: Particle swarm optimization–based finite-element (PSO-FE) method is introduced for the designs and analyses of the steel–concrete composite beams. After a brief explanation of the PSO-FE theory, the optimizations of shear ...
Crack Growth Behavior of Full-Scale Turbine Attachment Under Combined High and Low Cycle Fatigue
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Turbine attachments in the aero-engine are generally subjected to combined high and low cycle fatigue (CCF) loadings, i.e., low cycle fatigue (LCF) loading due to centrifugal and thermal loading stresses superimposed to ...
