(The American Society of Mechanical Engineers (ASME), 2006)Metallographic characterization is presented of thermal damage of Cr-coated steel in a fired cannon; Cr and Ta coated steel in a vented-erosion-simulator; and bulk Si3N4 in laser heating. Common ... -
Why Do Shallow Caps Deflect More Than Deep Ones?
(The American Society of Mechanical Engineers (ASME), 2006)The deflection of a clamped thin shell spherical cap is evaluated by the finite element method. Elastic material properties are assumed. The ratio of the center height to the base radius of ... -
The Effect of Pressure Relief Valve Blowdown and Fire Conditions on the Thermo-Hydraulics Within a Pressure Vessel
(The American Society of Mechanical Engineers (ASME), 2006)In the summers of 2000 and 2001, a series of controlled fire tests were conducted on horizontal 1890liter (500 US gallon) propane pressure vessels. The test vessels were instrumented with ... -
Hydraulic Testing of Ordnance Components
(The American Society of Mechanical Engineers (ASME), 2006)This paper describes a range of hydraulic fatigue and pressure tests carried out on gun barrels and ordnance components in support of weapons research and development programs. Cyclic testing ... -
The Influence of the Bauschinger Effect on the Yield Stress, Young’s Modulus, and Poisson’s Ratio of a Gun Barrel Steel
(The American Society of Mechanical Engineers (ASME), 2006)The Bauschinger effect (BE) was originally defined as the phenomenon whereby plastic deformation causes a loss of yield strength restraining in the opposite direction. The Bauschinger effect ... -
Application of an Enhanced RBI Method for Petrochemical Equipments
(The American Society of Mechanical Engineers (ASME), 2006)The American Petroleum Institute guideline provides a methodology for calculating the risks of equipments installed in refineries or petrochemical plants. However, especially in connection with ... -
