In the wake of the catastrophic failure of a low-pressure (LP) turbine disk at the Hinkley Point Nuclear Station in 1969, considerable research and development has been devoted to the prob...

Phasor measurement units (PMUs) are rapidly being installed across the USA as part of the DOE Smart Grid Investment Grant (SGIG) programs. Within three years there are expected to be over 1000 PMUs installed by nine SGIG grantees. However, there will

The application of recovery creep theory to the prediction of cyclic loading and heating response of a specific high temperature alloy is illustrated for four different cyclic shapes. It is shown that a satisfactory approximation to the quasi-steady

We interpret the findings of the present study and other studies reported here to indicate that alterations of renal outer to inner cortical blood flow distribution develop in the early postburn period. These alterations are similar to those observed

A plasticity theory is developed for a specific type of material characterized by coplanar motion of dislocation. Several results of the theory are given which make an experimental evaluation of the theory straightforward. The results of a limited ex

Room temperature fatigue crack initiation and propagation in the wrought nickel-base superalloy Udimet 700 were investigated with electropolished and glass bead blasted material. Cracks were found to initiate at the surface along coherent annealing t

A simple relationship between the stress-strain curves during initial and reversed loading is shown to approximate closely the shape of hysteresis loops for several materials and test temperatures. This relationship is derived from the assumption of

An analysis of the statically indeterminate problem of the creep of a biaxially loaded, anisotropic hollow cylinder is presented. The anisotropy of the material leads to a nonuniform axial stress distribution which is evaluated by numerical technique

The two major problems in shear forming cylindrical blanks are buildup of metal ahead of the tool ring and diametral growth of the part. The process variables (feed per revolution, reduction, tool ring contour) beneficial to diametral fit unfortunate

The history of industrial process computer control now spans over 10 years. During this time control theory has transgressed from the frequency domain to the time domain, and yet few applications of these modern methods to industrial processes can be
