A Crack Arrest Test Using a Toughness Gradient Steel Plate
(The American Society of Mechanical Engineers (ASME), 1995)A crack arrest test was carried out using a toughness gradient steel plate with three layers to study the concept of crack arrest toughness. Four-point bending load with thermal shock was ... -
Deformation Plasticity Failure Assessment Diagram (DPFAD) for Materials With Non-Ramberg-Osgood Stress-Strain Curves
(The American Society of Mechanical Engineers (ASME), 1995)This paper presents a brief history of the evolution of the Central Electricity Generating Board’s (CEGB) R-6 failure assessment diagram (FAD) procedure used in assessing defects in structural ... -
Extending the Theory of Creep to Viscoplasticity
(The American Society of Mechanical Engineers (ASME), 1994)A viscoplastic theory is developed that reduces to creep theory analytically under steady-state conditions. A fairly simple model is constructed from this theoretical framework by defining material ... -
The Effect of Multiaxiality on the Evaluation of Weldment Strength Reduction Factors in High-Temperature Creep
(The American Society of Mechanical Engineers (ASME), 1994)The conventional way to define the weldment creep strength reduction factor is usually based on uniaxial creep data of weld metals and parent metals. In order to take the multiaxial effect ... -
Dynamics and Stability of Pipes Conveying Fluid
(The American Society of Mechanical Engineers (ASME), 1994)This paper deals with the dynamics and stability of simply supported pipes conveying fluid, where the fluid has a small harmonic component of flow velocity superposed on a constant mean value. ... -
An Approach to Account for Negative R-Ratio Effects in Fatigue Crack Growth Calculations for Pressure Vessels Based on Crack Closure Concepts
(The American Society of Mechanical Engineers (ASME), 1994)Current fatigue crack growth procedures in the commercial nuclear industry do not clearly specify how compressive loads are to be handled and, therefore, regulatory agencies usually recommend a ... -
Mechanical Behavior of Bolted Joints Under Steady Heat Conduction
(The American Society of Mechanical Engineers (ASME), 1994)Bolted joints in heat exchangers, cylinder heads in combustion engines, and so on are subjected to heat fluxes. It is necessary to examine the mechanical behavior of such bolted joints under ... -
Probability of Fracture for HFIR Pressure Vessel Caused by Random Crack Size or by Random Toughness
(The American Society of Mechanical Engineers (ASME), 1994)The probability of fracture (or the fracture fragility) for a range of internal pressure-pulses for the HFIR pressure vessel is obtained. The fracture is assumed to be caused by randomly ... -
A Study on Buried Pipeline Response to Fault Movement
(The American Society of Mechanical Engineers (ASME), 1994)This study investigates the buried pipeline response to strike slip fault movement. The large deflection pipe crossing the fault zone is modeled as an elastica, while the remaining portion of ... -
Avoiding Steam Bubble Collapse-Induced Water Hammer in the Auxiliary Piping of Steam Power Plants
(The American Society of Mechanical Engineers (ASME), 1994)The mechanisms of steam bubble collapse-induced water hammer are identified for nominally horizontal or inclined pipes. On the basis of these observations, two methods of preventing steam bubble ... -
Simplified Methods for Calculation of Redundant Moments and Forces at the Discontinuities in Pressure Vessels—Part II: Hemisphere—Shell and Shells of Different Thicknesses
(The American Society of Mechanical Engineers (ASME), 1994)Following a similar idea as described in Part I of this paper, the redundant bending moment and the redundant shearing force at the junctures of hemispherical/cylindrical shells and of cylindrical ... -
On the Characteristics of Rectangular Bolted Flanged Connections With Gaskets Subjected to External Tensile Loads and Bending Moments
(The American Society of Mechanical Engineers (ASME), 1994)This paper deals with the characteristics of a rectangular bolted connection of “T” shape with a gasket (filler plate), in which the flanges and a gasket (filler plate) are fastened with two ... -
A Displacement Measurement Method by Laser-Beam Scanning for Mapping the Interior Geometry of Pipes
(The American Society of Mechanical Engineers (ASME), 1994)This paper proposes a displacement measuring technique for detailed noncontact mapping of the interior geometry of pipes. The technique, which is based on optical measurement using triangulation, ... -
Life Assessment of Superheater/Reheater Tubes in Fossil Boilers
(The American Society of Mechanical Engineers (ASME), 1994)Creep rupture failure of superheater (SH)/reheater(RH) tubes is a major cause of forced outages of power boilers. A methodology developed recently by EPRI and its contractors has helped utilities ... -
A Review of Acoustic Vibration Criteria Compared to In-Service Experience With Steam Generator In-Line Tube Banks
(The American Society of Mechanical Engineers (ASME), 1994)Tube banks of operating steam generators were evaluated for resonant acoustic vibration in the transverse acoustic mode, using a number of published vibration criteria and a range of Strouhal ... -
Probabilistic Analysis of Fatigue Crack Propagation Under Random Loading
(The American Society of Mechanical Engineers (ASME), 1994)In order to predict the fatigue crack growth curve under random loading, an analytical model is proposed in this paper. In addition to the mean crack growth curve, the model also considers ... -
An Approximate Procedure for Solving Base-Isolated Structures
(The American Society of Mechanical Engineers (ASME), 1994)Dynamic analysis of several shear-type structures with base isolation indicates that the response of these structures follows their fundamental mode shape. Based on this observation, this paper ... -
Sloshing Impact Pressure in Roofed Liquid Tanks
(The American Society of Mechanical Engineers (ASME), 1994)A series of experiments were carried out in order to clarify the nonlinear sloshing phenomena in the reactor vessels of the pool-type LMFBRs, which may cause damages to the vessels or their ... -
