Abstract: The use of finite element calculations is assessed as a means of analysis of the strain relaxation data from a measurement of residual stress by a material removal method. This application ...

Abstract: The Incremental Strain, Average Stress, Power Series, and Integral methods are examined as procedures for determining non-uniform residual stress fields using strain relaxation data from the hole ...

Abstract: The Integral Method for calculating non-uniform residual stress fields using strain relaxation data from the incremental hole-drilling method is examined in detail. Finite element calculations are ...

Abstract: Uniaxial tension and compression stress-strain curves are simultaneously evaluated from load and surface strain data measured during a bending test. The required calculations for the uniaxial ...

Abstract: Many nuclear stations do not incorporate deaerators in their feedwater heating systems. To attain high turbine cycle performance without a deaerator, a drain pumping system is widely used for ...

Abstract: Power plant safety and relief value vent stacks have generally been sized according to the methods and design criteria published by Max W. Benjamin in the 1940s. Although the method might ...

Abstract: It has been known that drain pumps in nuclear power plants may suffer cavitation under transient turbine load reductions [1]. Although increasing the size and height of the drain tank can ...

Abstract: Experimental work was done rolling balls on flat plates and in V-grooves at loads and contact angles corresponding to usual thrust-bearing practice. It is shown that the spinning action of the ...
