WebAbstract Fatigue phenomenon is one of the main factors controlling the life of the steel bridges. And it is caused from accumulation of live load stress for long time under a normal condition rather than an extreme condition. In the steel plate girder railway bridge, a bending deformation is occurred on the effect of eccentric at the upper flange of inner girder. WebThis paper discusses a one-way fluid structural interaction (FSI) analysis and shape optimization of the impeller blades for a 15,000 HP centrifugal compressor using the …
