...Juha Toivola; Seppo Moilanen; Janne Tervokoski; Heikki Keinänen The soft deformable metallic rotating band of large caliber projectiles prevents the gas leakage between the gun tube wall and the shell body by the band pressure on contact surfaces during the launch cycle of the gun. High rotating...

...Shugen Xu; Weiqiang Wang; Yuliang Cui; Yan Liu In this paper, a developed solution structure theorem has been provided. It can be used to solve the wave equation about the structural response of cylinder under the dynamic pressure. This new approach also can be used to solve a batch of partial...

... of a three dimensional elastic body with no a priori assumption and the equilibrium of a segment deformed by bending moments. To verify the accuracy of the equivalent elastic constants, a linear static analysis of sandwiched aluminum plates subjected to lateral pressure is carried out. The results...

...Yasin Kisioglu This study addresses the prediction of the burst pressures and burst failure locations of the vehicle toroidal liquefied petroleum gas (LPG) fuel tanks using both experimental and finite element analysis (FEA) approaches. The experimental burst test investigations were carried out...

...Toshiyuki Sawa; Ryo Kurosawa; Wataru Maezaki The contact gasket stress distributions in a rectangular box-shape bolted flange connection with a compressed sheet gasket subjected to internal pressure were analyzed using the finite element method. Leakage tests were also conducted for an actual...

... pressure is held for 24 h to ensure that the pipeline is leak free. Ideally the pressure should remain constant, but this is practically impossible due to changes in temperature. Pressure and temperature of the pipelines are recorded continuously and evaluated at the end of the test. The pressure drop...

... pressure creep tests were conducted on P91 steel longitudinal welded tubes to characterize the evolution of creep damage with time and to evaluate a life prediction method. Interrupted creep tests were performed for damage observation in addition to rupture tests. Three dimensional finite element creep...

...P. Moussou; R. J. Gibert; G. Brasseur; Ch. Teygeman; J. Ferrari; J. F. Rit Pressure relief valves in water pipes are known to sometimes chatter when the inlet pressure slightly exceeds the set pressure. While these devices are responsible for numerous fatigue issues in process industries...

...Kleio Avrithi; Bilal M. Ayyub Nuclear pipes are designed to withstand primary membrane stresses generated by internal pressure according to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code, Section III, Parts NB-3641, NC-3641, and ND-3641, which uses...

...Kleio Avrithi; Bilal M. Ayyub Nuclear safety-piping is designed according to the ASME Boiler and Pressure Vessel Code, Sections III, NB-, NC-, and ND-3600 that use the allowable stress design method (ASD). The potential use instead of reliability-based design equations for nuclear piping could...

...Masahiro Watanabe, Associate Professor; Nobuyuki Kobayashi, Professor; Yuichi Wada, Graduate Student This paper deals with the theoretical stability analysis and experimental study of flexible bellows subjected to periodic internal fluid pressure excitation. The bellows studied in this paper...

.... The mass and stiffness matrices of each structural element are derived by exact analytical integration. In Section 3, the velocity potential, Bernoulli’s equation and impermeability condition have been applied to the shell fluid interface to obtain an explicit expression for fluid pressure which yields...

...J. Błachut; P. Wang The paper considers barreling of a mild steel cylindrical shell as a way of improving its load carrying capacity when subjected to static external pressure. Numerical results show that the load carrying capacity can be increased from 1.4 to 40 times above the load capacity...

...Hashem M. Mourad; Maher Y. A. Younan The behavior of a pipe bend, with bend factor h = 0.1615 ( D = 16 in. , R = 24 in. and t = 0.41 in. ) , subjected to out-of-plane bending and internal pressure is studied, taking geometric and material nonlinearity into account, using the finite element code...
