Plastic Buckling of Short Vertical Cylindrical Shells Subjected to Horizontal Edge Shear Loads
(The American Society of Mechanical Engineers (ASME), 1985)Vertical liquid-filled cylindrical shells which are subjected to horizontal seismic loads can fail by buckling in shear. One example where this might arise in the nuclear industry is with the ... -
A Simplified Finite Element for Added Mass and Inertial Coupling in Arrays of Cylinders
(The American Society of Mechanical Engineers (ASME), 1985)A simplified finite element has been developed for modeling the added mass and inertial coupling arising when clusters of cylinders vibrate in a quiescent fluid. The element, which is based ... -
The Bending of an Orthotropic Membrane Wall Supported at Arbitrary Points
(The American Society of Mechanical Engineers (ASME), 1985)For large industrial boilers and boilers for Conventional Power Plants extra supporting of the rear wall (designated as “membrane wall”) of the furnace is necessary. By supporting the wall at ... -
A Mechanistic Approach to Remanent Creep Life Assessment of Low Alloy Ferritic Components Based on Hardness Measurements
(The American Society of Mechanical Engineers (ASME), 1985)Creep damage leading to failure in low alloy ferritic steels at service operating conditions results from: (i) structural coarsening leading to a continuous reduction in creep strength during ... -
A Simplified Analysis Method for Complex Piping Systems in Elastic-Plastic-Creep Range
(The American Society of Mechanical Engineers (ASME), 1985)The present paper describes a simplified finite element method for analysis of behavior of complex piping systems under elevated temperature. Elastic-plastic-creep deformations of a piping system ... -
