High Pressure Generation Using Underwater Explosion of a Spiral Explosive in a Conical Vessel
(The American Society of Mechanical Engineers (ASME), 2004)An explosive configuration was studied so that the underwater shock wave converges at the tip of the explosive, and a three-dimensional spiral configuration was obtained. This spiral configuration ... -
Buried Pipe Modeling With Initial Imperfections
(The American Society of Mechanical Engineers (ASME), 2004)A formulation using the finite element method is presented in this paper to analyze stresses and displacements of underground pipelines with initial imperfections. The formulation includes both ... -
A Method for Producing Extra-High Dynamic Pressure Due to the Efficient Use of High Explosive
(The American Society of Mechanical Engineers (ASME), 2004)In the material processing such as shock synthesis and powder consolidation by shock waves the method for generating dynamic pressure is a vital factor for the quality of the final recovered ... -
Fluid-Elastic Instability in a Tube Array Subjected to Uniform and Jet Flow
(The American Society of Mechanical Engineers (ASME), 2004)A wind tunnel study was carried out to investigate the fluidelastic stability of a model heat exchanger tube array subjected to a uniform cross-flow of air and a concentrated jet flow of air ... -
Stress Intensity Factors for a Curved-Front Internal Crack in an Autofrettaged Tube With Bauschinger Effect
(The American Society of Mechanical Engineers (ASME), 2004)Pressure vessel steels exhibit the Bauschinger effect that significantly reduces post-autofrettage residual compressive hoop stresses in the near-bore region in comparison with ‘ideal’ (elastic-perfectly ... -
A Critical Examination of Sachs’ Material-Removal Method for Determination of Residual Stress
(The American Society of Mechanical Engineers (ASME), 2004)Sachs’ method is an experimental procedure used primarily in the determination of residual stresses in autofrettaged thick cylinders. In its usual form it involves fixing axial and hoop direction ... -
Lower Bound Limit Load Determination: The mβ-Multiplier Method
(The American Society of Mechanical Engineers (ASME), 2004)The existing lower bound limit load determination methods, that are based on linear elastic analysis such as the classical and mα-multiplier methods, have a dependence on the maximum equivalent ... -
Reference Stress Based Approach to Predict Failure Strength of Pipes With Local Wall Thinning Under Single Loading
(The American Society of Mechanical Engineers (ASME), 2004)This paper proposes a new method to estimate failure strength of a pipe with local wall thinning. The method is based on the equivalent stress averaged over the minimum ligament in the locally ... -
Yield Criterion for Thin Perforated Plates With Square Penetration Pattern
(The American Society of Mechanical Engineers (ASME), 2004)Second and fourth order polynomials describing the yield criterion for perforated plates with square penetration pattern were developed following the methodology shown by Hill (1950) and later ... -
Nondestructive Evaluation of FRP Design Criteria With Primary Consideration to Fatigue Loading
(The American Society of Mechanical Engineers (ASME), 2004)Design of FRP tanks and pressure vessels is based on criteria developed in the late 1960s using materials and procedures that represented the state of the art at the time. Maximum strain has ... -
The Use of “Fitness for Service” Assessment Procedures to Establish Allowable Flaw Sizes in Steel Cylinders
(The American Society of Mechanical Engineers (ASME), 2004)As part of the U.S. Department of Transportation safety regulations, seamless steel cylinders that are used to transport high-pressure gases are required to be periodically retested during their ... -
Failure Strength Assessment of Pipes With Local Wall Thinning Under Combined Loading Based on Finite Element Analyses
(The American Society of Mechanical Engineers (ASME), 2004)Failure assessment of a pipe with local wall thinning draws increasing attention in the nuclear power plant industry. Although many guidelines have been developed and are used for assessing the ... -
Stress Concentration Factors of Cross-Bores in Thick Walled Cylinders and Blocks
(The American Society of Mechanical Engineers (ASME), 2004)The purpose of this paper is to investigate the stress concentration in stress fields around crossbores for closed-end thick-walled square blocks and cylindrical shells using the finite element ... -
Dynamic Stability of Flexible Bellows Subjected to Periodic Internal Fluid Pressure Excitation
