Abstract: A new, unified model simulates many of the structurally significant deformation phenomena associated with both creep and short-time plasticity, including cyclic hardening/softening, Bauschinger effect, ...

Abstract: For the deformation model developed in Part I, material constants are calculated from standard test data on type 304 stainless steel. With them, simulations are made of various types of tests, ...

Abstract: Progress toward developing life models for simulating the behavior of thermal barrier coatings in aircraft gas turbine engines is discussed. A preliminary laboratory model is described as are ...

Abstract: Measurements of local heat-transfer coefficients in the fully established oscillating turbulent boundary layer over a flat plate are reported. In the range of frequencies from 0.1 to 200 cps ...

Abstract: The circuit and application of an inexpensive simple linearized hot wire anemometer especially suited to turbulence research in incompressible media is described. Special features of the design ...

Abstract: Thermal barrier coating life models developed under the NASA Lewis Research Center’s Hot Section Technology (HOST) program are summarized. An initial laboratory model and three design-capable ...

Abstract: A combination of the numerical technique of Chorin for the solution of the Navier-Stokes equations and a transformation of the initial value problem to a boundary value problem is shown to ...

Abstract: Litigation in the construction industry usually involves opinions about the “standard of care.” This paper discusses the problems with individual opinions, and describes three basic methods for determining a “standard of ...

Abstract: The gas film stiffness and damping properties for a spiral grooved mechanical face seal in a flexibly mounted stator configuration are computed using the step jump method and a novel direct ...
