Valve Stroking to Control Water Hammer Transients Using Dynamic Programming
(The American Society of Mechanical Engineers (ASME), 1987)Fluid transients in a pipeline caused by valve operation can be minimized by operating the valve in an optimally prescribed manner, in a given time of closure (t c > 2L /a ). Dynamic ... -
An Extrapolation Procedure of Creep Data for St Determination: With Special Reference to Cr-Mo-V Steel
(The American Society of Mechanical Engineers (ASME), 1987)A predictive rule for long-term creep data, necessary to determine S t of the ASME Code, was proposed with special reference to a Cr-Mo-V steel. This rule can predict long-term creep curves ... -
Virtual Crack Extension Method for Energy Release Rate Calculations in Flawed Thin Shell Structures
(The American Society of Mechanical Engineers (ASME), 1987)The calculation of the energy release rate, G , by the virtual crack extension method has been used extensively in the literature over the last few years. A formulation and implementation of ... -
Statistical Methods Applied to Fuel Rod Bow Analysis
(The American Society of Mechanical Engineers (ASME), 1987)An extensive data base was used to arrive at an empirical “best estimate” model for predicting fuel rod bow as a function of burnup. The best estimate rod bow predictions were bounded ... -
Dynamic Photoelastic Study of Crack-Wave Interaction in Thick-Walled Rings
(The American Society of Mechanical Engineers (ASME), 1987)A series of photoelastic experiments were conducted to study crack-wave interaction in thick-walled rings. Particular attention was paid to the initiation, propagation and branching of small flaws ... -
Fatigue Life Estimates for a Notched Member in a Corrosive Environment
(The American Society of Mechanical Engineers (ASME), 1987)It is often assumed that the effects of an aggressive environment can be included in fatigue life estimation procedures by determining the material properties in the environment and at the ... -
Impact Simulation of Process Equipment Tubes and Support Plates—A Numerical Algorithm
(The American Society of Mechanical Engineers (ASME), 1987)The occurrence of flow-induced vibration fretting wear in process equipment such as heat exchangers and steam generators accounts for the majority of the failures due to vibration. One of the ... -
