... are made for coating and firing conditions that correspond to modem cannon firing. This comparison suggests changes in cannon bore coatings to handle the more extreme thermal conditions in modern cannon firing, including thicker or more durable thermal barrier coatings to minimize thermal stresses...

... of ensembles as direct measurements with subjects. Dynamic measurements of heat transfer properties appear to present reliable and realistic values for clothing thermal performance and should be used with prediction models and assesment methods of thermal stress. Thermal stress insulation evaporative...

... Numerical and analytical methods for calculating thermal stresses and deformations in a flat plate connected to a cooled wall with an intermediate layer of solder or adhesive are proposed. In the numerical method, the nonisothermal flow theory for layer material was used. In the analytical...

... as 4% below resting levels and the carbon dioxide level increased by a similar amount. Finally, thermal stress is clearly evident, especially in the 43°C (110°F) tests. State-of-the-art design techniques in whole body suits do not provide solutions to these problems. Therefore, it has been necessary...

... The concentration of thermal stress in a shaft subjected to a ramp surface temperature change has been investigated. The concentration occurs at a step change in shaft diameter, and the temperature and stress responses are calculated by the finite element method. A thermal stress concentration...

... crack initiation, and complete fracture of both unnotched and notched fatigue specimens. Sample output tables are shown, together with results for two typical problems: ( a ) thermal-mechanical fatigue of bar specimens of the tantalum alloy T-111 and ( b ) thermal-stress fatigue of wedge specimens...

... The comparative thermal-stress fatigue resistances of 26 nickel- and cobalt-base alloys were determined by fluidized bed tests. Cycles to cracking differed by almost three orders of magnitude for these materials, with directional solidification and surface protection showing definite benefit...
