Mass, Stiffness, and Damping Identification for a Pressurized Water Reactors Fuel Assembly by a Proper Orthogonal Decomposition Method
(The American Society of Mechanical Engineers (ASME), 2014)In this paper, dynamic tests of a fuel assembly subjected to an axial flow are presented. Tests are performed for various flow conditions, at several displacement amplitudes. The first four modes of the fuel assembly are ... -
Stress Intensification Factors for Fabricated Lateral Piping Connections
(The American Society of Mechanical Engineers (ASME), 2014)Stress intensification factors (SIFs) are published in the piping codes for tees; branch connections where the branch intersects the header pipe at 90 deg. These factors when multiplied by the nominal stress provide a ... -
Methodology for the Optimization of Bolting Sequences for Wind Generator Flanges
(The American Society of Mechanical Engineers (ASME), 2014)In bolted joints, bolts are tightened to a uniform preload in order to improve their operational behavior. This preload is not easy to achieve due to several phenomena that occur during the tightening sequence; in the case ... -
