...H.-T. Liu; Y. Hovanski; M. E. Dahl Laboratory tests were conducted to determine the fatigue performance of abrasive-waterjet- (AWJ-) machined aircraft titanium. Dog-bone specimens machined with AWJs were prepared and tested with and without sanding and dry-grit blasting with Al 2 O 3...

...Rolf R. de Swardt; Tony D. Andrews 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 tube strength. Finite element analyses were then done of a midwall...

... of removal on redistribution of residual stresses at the bore. Resulting stresses after machining are also calculated by the VMP method using actual behavior. It is shown that the final residual stress field differs significantly if actual unloading behavior is used. The tests are carried out in fatigue...

...Amer Hameed; R. D. Brown; J. G. Hetherington A multi-linear kinematic, two dimensional finite element model incorporating Bauschinger effect, developed using ANSYS commercial software is used to determine the effect of machining both at the bore and at the outside diameter, on the depth of yield...

... occur if the sum of residual stress and applied stress exceeds a critical threshold tensile stress. Residual stresses developed by prior machining and welding can accelerate or retard SCC depending on their sign and magnitude. The residual stress, cold work and yield strength distributions on the inside...

...Frantisek L. Eisinger, Mem. ASME Impellers of air, gas, or steam moving rotating machinery are exposed to acoustic pressure loading (pressure pulsations) from acoustic waves generated in the gaseous medium from flow within the machine casing. The acoustic waves and the impeller structure contain...

...Mohamed Hashish, Fellow ASME Waterjet technology development for 600-MPa (87-Ksi) operations involves efforts on machining process development, pumps, plumbing, nozzles, and machining systems development. In this paper, data will be presented on cutting with water and abrasive waterjet...

...M. Perl, Professor and Associate Dean of Engineering, An analytical model for predicting the level of autofrettage following either inner, outer, or combined machining of a gun barrel is developed based on Hill’s (Hill, R., 1950, The Mathematical Theory of Plasticity, Clarendon Press, Oxford, U.K...

...M. Ramulu; S. Kunaporn; D. Arola; M. Hashish; J. Hopkins An experimental study was conducted to determine the influence of high-pressure waterjet (WJ) peening and abrasive waterjet (AWJ) machining on the surface integrity and texture of metals. A combination of microstructure analysis...
