Temperature-Induced Stresses in Solids of Elementary Shape

Temperature-Induced Stresses in Solids of Elementary Shape

Date: June 21, 1960
Creator: Adams, Leason H.
Description: Report discussing how solids subjected to non-uniform temperature change develop internal stresses determined by, (1) the temperature distribution within the solid, and (2) certain physical constants of the material. For two varieties of heating, the equations determining stress have been put in convenient form for practical use, and tables of certain temperature functions show how to determine stresses in a slab, in a cylinder, or in a sphere subjected to either of two modes of heating. The temperature-distribution tables independently provide a useful means for the ready estimation of temperature gradients.

Tensile and Impact Properties of Selected Materials From 20 to 300 ºK

Tensile and Impact Properties of Selected Materials From 20 to 300 ºK

Date: June 28, 1963
Creator: Warren, K. A.
Description: Report giving the tensile and impact properties of structural materials that were experimentally determined at temperatures from 20 to 300 ºK. Tensile properties of a few materials were also determined at 4 ºK. The properties experimentally determined were the yield strength, tensile strength, elongation, and reduction of area, the stress versus strain curve, and the impact energy. The test equipment and procedures are described. The individual data are presented in tables, and the average results are displayed in graphs.

Theory and Methods of Optical Pyrometry

Theory and Methods of Optical Pyrometry

Date: March 1, 1962
Creator: Kostkowski, H. J.
Description: Report reviewing the theoretical methods of optical pyrometry and the application of these methods at the National Bureau of Standards in realizing, maintaining and distributing the International Practical Temperature Scale above 1063 ºC is presented. In the theoretical presentation, the concepts of effective and mean effective wavelengths are introduced, and various equations relating these parameters to each other and other physical quantities are derived. The methods presentation discusses important features of precision visual optical pyrometers, experimental procedures, and results of primary and secondary calibrations of optical pyrometers.
