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 ...

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 ...

Abstract: The uniaxial Bauschinger effect has been evaluated in several high strength steels being considered for armament application. The steels investigated include ASTM A723 (1130 and 1330 MPa), PH ...

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 ...

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 ...

Abstract: Analytical and numerical stress analyses of the autofrettage process have made great strides in the last few years. The major challenge is no longer the stress analysis process but the ...

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, ...

Abstract: Results from four groups of full-scale pressure vessel service simulation tests are described and analyzed using Paris fatigue life modeling. The objective is to determine how the vessel and ...
