Abstract: An extensive analysis of the fatigue life of a typical modern autofrettaged smoothbore tank barrel, cracked either internally or externally, in terms of the initial crack depth and shape, type and level of autofrettage, ...

Abstract: The favorable residual stress field generated by the autofrettage process is increasing the barrel's capacity to withstand pressure during firing—defined as the reloading phase. There are two principal autofrettage ...

Abstract: The design of a gun barrel aims at maximizing its firing power, determined by its safe maximum pressure (SMP)—the maximal allowed firing pressure—which is considerably enhanced by inducing a favorable residual stress field ...

Abstract: During the firing of guns, the barrel undergoes two major damaging processes: wear of its inner surface and internal cracking. Barrel's are condemned based on either the increase of their internal diameter due to wear or ...

Abstract: The theoretical modeling of the rotational autofrettage of a thick-walled cylinder based on the generalized plane strain assumption has been presented in part I of the paper. In order to access the potentiality of the ...

Abstract: An investigation was made into the fatigue properties of L485MB (X70) pipeline steel after 13 yr of exploitation as a crude oil pipeline material. Fatigue tests in zerototension loading were carried out (i) in air, (ii) ...

Abstract: The benefits of autofrettage for thickwalled cylindrical vessels as a means of improving the vessel's durability and sustainability have been addressed in the published literature. However, the presence of the Bauschinger ...

Abstract: For the investigation of cracked problems in thickwalled pressurized cylindrical vessels, the displacementbased finite element method has become one of the main computational tools to extract stress intensity results for ...

Abstract: In recent years, a few new methods of achieving autofrettage in thick-walled hollow cylinders have been developed. Rotational autofrettage is one of the new methods proposed recently for prestressing thick-walled cylinders. ...

Abstract: The evaluation of equivalent temperature fields for cylindrical and spherical pressure vessels to imitate autofrettage-induced residual stresses has been successfully implemented in studying crack growth in autofrettaged ...
