Validation of Inelastic Analysis by Full-Scale Component Testing
(The American Society of Mechanical Engineers (ASME), 1987)This paper compares theoretical and experimental results for full-scale, prototypical components tested at elevated-temperatures to provide validation for inelastic analysis methods, material models, ... -
Experimental Studies on Earthquake Response Behavior of Cylindrical Tanks
(The American Society of Mechanical Engineers (ASME), 1987)A series of dynamic tests for the seismic behavior of ground-supported liquid storage tanks are evaluated and compared with previous theoretical studies. Two model tanks were subjected to shaking ... -
Progress in Collapse Analyses
(The American Society of Mechanical Engineers (ASME), 1987)In the field of finite element structural analysis, the computation of collapse states of structures prone to unstable behavior has long been considered a difficult if not intractable problem. ... -
A Method for Correlating Severity of Different Seismic Qualification Tests
(The American Society of Mechanical Engineers (ASME), 1987)A general methodology has been developed for correlating the severity of various seismic qualification motions that can have very different dynamic characteristics. The approach is based on a ... -
Creep Buckling Analyses of Circular Cylindrical Shells Under Axial Compression—Bifurcation Buckling Analysis by the Finite Element Method
(The American Society of Mechanical Engineers (ASME), 1987)The finite element method is applied to the creep buckling of circular cylindrical shells under axial compression. Not only the axisymmetric mode but also the bifurcation mode of the creep ... -
Plastic Strain Concentration in a Cylindrical Shell Subjected to an Axial or a Radial Temperature Gradient
(The American Society of Mechanical Engineers (ASME), 1987)Plastic strain concentration factors for use in elastic fatigue analyses (like K e in ASME Code) are usually overly conservative, but may be unsafe in certain cases. Especially for unnotched ... -
A New Technique for Approximating the Stress in Pad-Type Nozzles Attached to a Spherical Shell
(The American Society of Mechanical Engineers (ASME), 1987)The generally applicable approximate analysis for pad-type nozzles was shown statistically to be reliable through the use of the design of experiments. The focus was on membrane stresses due ... -
Creep Damage in 17–12 SPH Stainless Steel Notched Specimens: Metallographical Study and Numerical Modeling
(The American Society of Mechanical Engineers (ASME), 1987)Creep-rupture tests on notched specimens of 17–12 SPH stainless steel are performed at elevated temperature (600°C). Metallographic examination allows the quantitative estimation of the ... -
Weld Investigation of Nuclear Power Plant Pressure Vessels
(The American Society of Mechanical Engineers (ASME), 1987)Welds in nuclear power plant pressure vessels, which were in accordance with the ASME Boiler and Pressure Vessel Code, though not with some other codes, were investigated nondestructively over ... -
A Review of Methods of Equivalent Damping Estimation From Experimental Data
(The American Society of Mechanical Engineers (ASME), 1987)The computational problems associated with the estimation of damping, particularly in piping systems, is discussed in detail and appropriate procedures are recommended to minimize their impact. ... -
Subspace Iteration for Eigen-Solution of Fluid-Structure Interaction Problems
(The American Society of Mechanical Engineers (ASME), 1987)The subspace iteration method, commonly used for solving symmetric eigenvalue problems in structural dynamics, can be extended to solve nonsymmetric fluid-structure interaction problems in terms ... -
Nonlinear Response of U-Tubes to a Differential Axial Movement Between Two Legs
(The American Society of Mechanical Engineers (ASME), 1987)The deflections and the stresses in U-tubes due to differential thermal expansion between two legs are nonlinear functions of the thermal loading even with linear elastic materials. The nonlinear ... -
