RISCritical Fracture Processes in Army Cannons: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fast fracture in cannons can be well described using elastic-plastic fracture toughness, in combination with comparisons of cannon section size relative to the size required to maintain plane ...
Second Special Issue on Pressure Vessels Technology Applied to Gun Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The previous open conference with a focus on large caliber gun tube design took place in Oxford, England, in 2002; this gave rise to the August 2003 special issue of JPVT. A second Oxford ...
Stress and Fatigue Life Modeling of Cannon Breech Closures Including Effects of Material Strength and Residual Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laboratory fatigue life results are summarized from several test series of high-strength steel cannon breech closure assemblies pressurized by rapid application of hydraulic oil. The tests were ...
Stress and Fracture Analysis of Ceramic Lined, Composite or Steel Jacketed Pressure Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stress and fracture analysis of ceramic-lined cannon pressure vessels is described, for a Si3N4 or SiC liner and A723 steel or carbon-epoxy jacket and with an initial residual interface pressure ...
Finite Element Investigation of Bauschinger Effect in High-Strength A723 Pressure Vessel Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Stresses Within Compound Tubes Comprising a Steel Liner and an External Carbon-Fiber Wrapped Laminate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is increasing interest in techniques that permit weight reduction of thick cylinders, particularly gun barrels. The method examined within this paper involves the external wrapping of a ...
Characterization of Steels Using a Revised Kinematic Hardening Model Incorporating Bauschinger Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new variant of the nonlinear kinematic hardening model is proposed which accommodates both nonlinear and linear strain hardening during initial tensile loading and reduced elastic modulus during ...
Special Issue on Pressure Vessels Technology Applied to Gun Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: and to Professor S. Zamrik, Professor M. Perl and Ms. D. Bierly who made possible this special journal issue. John G. Hetherington RMCS, University of Cranfield, UK, Anthony P. Parker RMCS, University of Cranfield, UK, John H...
Impact of Intensity of Residual Stress Field Upon Reyielding and Re-Autofrettage of an Autofrettaged Thick Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Re-autofrettage has been identified as a significant, cost-effective method to achieve higher reyield pressure (RYP) and/or weight reduction in large caliber gun tubes. For a given overstrain, ...
Thermomechanically Controlled Erosion in Army Cannons: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
