...Wei Wang; Liang Chen; Caidong Guo In order to investigate the strength design problem of the brazed aluminum plate-fin heat exchanger header under complex external piping loads, the limit load interactions of the header under combined piping loads are studied in this paper. To establish the limit...

...Mohamed Hashish Increasing the pressure of abrasive waterjet, while fixing the jet power, increases the jet’s power density and thus the cutting speed may increase. This was observed for steel, aluminum, and stone cutting. It was also observed that the kerf taper is less for higher pressure jets...

... = 1209   m / s Penetration results obtained using ALEGRA/SHISM were presented for several ideal and nonideal impact conditions. These studies considered impacts of steel penetrators into aluminum targets. The results suggest that excellent agreement between predicted and measured...

... analysis computer program was used to determine the three-dimensional dynamic stresses that result from pipe wall vibration at a distance from the end of a pipe, during a water-hammer event. The analysis was used to model a moving shock wave in a pipe, using a step pressure wave. Both aluminum and steel...

...Tong Wa Chao; Joseph E. Shepherd The role of loading rate and fluid properties in the fracture of piping under internal explosions is an important issue for designers and accident analysis. This was examined by fracture experiments on thin-walled and preflawed aluminum 6061-T6 tubes. The tubes were...

...Won-Bae Na; Tribikram Kundu, Fellow ASME Underwater pipeline inspections are conducted using ultrasonic cylindrical guided waves in the laboratory environment. Three different types of mechanical defects—gouge, removed metal, and dent—are fabricated in small-diameter, 22.22-mm, aluminum pipes...

... are conducted using three-dimensional FEM as an elastic contact problem. The analytical objects are pipe flanges specified in JIS B 2238 with an aluminum gasket inserted. The validity of the numerical procedures proposed here is ascertained by experiment. 2 Bolt number corresponding to the bolt-up sequence...

..., 12, and 8-mm-dia bolts, as the magnitude of the external load was increased. The external load was increased from zero to the value that caused the bolt force to equal its proof strength. The member stiffness for aluminum members decreased by 22.7 and 29.9 percent for the 24 and 20-mm bolts. The cast...
