Laboratory Heat Transfer Experiments on a 155mm Compound Gun Tube With Full Length Integral Mid-Wall Cooling Channels
(The American Society of Mechanical Engineers (ASME), 2006)A 155 mm compound gun barrel with full-length integral mid-wall cooling channels was manufactured and connected to a purpose built heat exchanger. Laboratory testing of this system was carried ... -
Carbon Fiber/Thermoplastic Overwrapped Gun Tube
(The American Society of Mechanical Engineers (ASME), 2006)The emphasis on lightweight large-caliber weapons systems has placed the focus on the use of advanced composite materials. Using composite materials not only directly removes weight from the gun ... -
Projectile Driving Band Interactions With Gun Barrels
(The American Society of Mechanical Engineers (ASME), 2006)This paper discusses results from a series of trials carried out to determine the effect of the projectile driving band on the stress applied to a 155mm gun barrel during firing. The ... -
Design Considerations for Electromagnetic Railguns
(The American Society of Mechanical Engineers (ASME), 2006)Electromagnetic (EM) railguns are similar to powder guns in that both provide an accelerative force to the projectile, while accepting the resulting recoil impulse. They are designed to contain ... -
Probabilistic Modeling for Ceramic Lined Gun Barrels
(The American Society of Mechanical Engineers (ASME), 2006)Designers of advanced gun systems have been tasked with increasing barrel life in the face of the extreme erosion and wear of the interior ballistics environment. The addition of refractory ... -
A Critical Examination of Stresses Within and Around Coatings
(The American Society of Mechanical Engineers (ASME), 2006)In many cases apparently complex interactions between a coating and a substrate may be reduced to a combination of two simple loading scenarios, namely, constant direct stress and linearly ... -
The Influence of the Bauschinger Effect on 3D Stress Intensity Factors for Internal Radial Cracks in a Fully or Partially Autofrettaged Gun Barrel
(The American Society of Mechanical Engineers (ASME), 2006)The influence of the Bauschinger effect (BE) on the three-dimensional, mode I, stress intensity factor (SIF) distributions for arrays of radial, internal, surface cracks emanating from the bore ... -
Characterization and Comparison of Magnetron Sputtered and Electroplated Gun Bore Coatings
(The American Society of Mechanical Engineers (ASME), 2006)The demands to increase range, rate of fire, and muzzle velocity have resulted in increased wear and erosion problems in gun tubes. To increase the service life of gun tubes, a number of ... -
Gun Barrel Erosion—Comparison of Conventional and LOVA Gun Propellants
(The American Society of Mechanical Engineers (ASME), 2006)The research department Energetic Materials within TNO Defence, Security and Safety is involved in the development and (safety and insensitive munitions) testing of conventional (nitro cellulose ... -
Optimum Autofrettage and Shrink-Fit Combination in Multi-Layer Cylinders
(The American Society of Mechanical Engineers (ASME), 2006)The interest in the use of layered cylinders that combine autofrettage and shrink fit in order to extend fatigue lifetimes is increasing. As the number of layers increases, the sequential order ... -
Stress Analysis of Autofrettaged Midwall Cooled Compound Gun Tubes
(The American Society of Mechanical Engineers (ASME), 2006)Analytical solutions for shrink-fit compound gun tubes were used to study the effects of the liner/sleeve interface diameter, the radial interference, and the effect of machining tolerances on ... -
Assembly of Compound Tubes Under Hydraulic Pressure
(The American Society of Mechanical Engineers (ASME), 2006)This paper describes a method for inserting a tapered liner into a sleeve while the latter is expanded by hydraulic pressure. The technique avoids many of the limitations associated with ... -
Finite Element Investigation of Bauschinger Effect in High-Strength A723 Pressure Vessel Steel
(The American Society of Mechanical Engineers (ASME), 2006)The Bauschinger effect has been evaluated in high-strength pressure vessels. A simple initial test suggested that a biaxial Bauschinger effect was present and that it was different from previously ... -
Effect of Bauschinger Effect and Yield Criterion on Residual Stress Distribution of Autofrettaged Tube
(The American Society of Mechanical Engineers (ASME), 2006)Many analytical and numerical solutions for determining the residual stress distribution in autofrettaged tube have been reported. The significance of the choice of yield criterion, the Bauschinger ... -
A Comparison of Methods for Predicting Residual Stresses in Strain-Hardening, Autofrettaged Thick Cylinders, Including the Bauschinger Effect
(The American Society of Mechanical Engineers (ASME), 2006)High-pressure vessels, such as gun barrels, are autofrettaged in order to increase their operating pressure and fatigue life. Autofrettage causes plastic expansion of the inner section of the ... -
