Proposal for Calculations of Flat Oval Pipes Under Internal Pressure Under Consideration of Material Plastification
(The American Society of Mechanical Engineers (ASME), 1997)In the wall of an oval pipe, additional to the circumferential forces, shear forces and bending moments occur under internal pressure load. Under this condition, the bending stresses in certain ... -
An Analysis of the Two-Bar Ratcheting Behavior Using the Viscoplasticity Theory Based on Overstress (VBO)
(The American Society of Mechanical Engineers (ASME), 1997)The ratcheting behavior of the “unsymmetric two-bar system” was investigated by numerical experiments. The two bars are restrained to the same length and are subjected to a constant load. One ... -
Modeling of Multiaxial Creep Behavior for Incoloy 800 Tubes Under Internal Pressure
(The American Society of Mechanical Engineers (ASME), 1997)In order to validate the long-term behavior of fast breeder reactor steam generator tubes, a creep test monitoring program has been undertaken. A series of over one hundred tests was performed ... -
Corrosion Fatigue Crack Growth in Clad Low-Alloy Steels—Part I: Medium-Sulfur Forging Steel

An Axisymmetric Method of Elastic-Plastic Analysis Capable of Predicting Residual Stress Field
(The American Society of Mechanical Engineers (ASME), 1997)Linear elastic solution of an axisymmetric boundary value problem is used as a basis to generate its inelastic solution. This method treats the material parameters as field variables. Their ... -
The Significance of Crack Depth (a) and Crack Depth-to-Width Ratio (a/W) With Respect to the Behavior of Very Large Specimens
(The American Society of Mechanical Engineers (ASME), 1997)Previous studies have shown that there is an increase in cleavage fracture toughness of laboratory specimens with shallow flaws compared with those laboratory specimens having deep flaws. Typical ... -
A Stress Analysis of a Taper Hub Flange With a Bolted Flat Cover
(The American Society of Mechanical Engineers (ASME), 1997)A bolted connection consisting of a cover on a pressure vessel flange with a metallic flat gasket on raised faces is analyzed as a four-body contact problem using axisymmetrical theory of ... -
Round Robin Calculations of Collapse Loads—A Torispherical Pressure Vessel Head With a Conical Transition
(The American Society of Mechanical Engineers (ASME), 1997)Round robin calculations of collapse loads for a pressure vessel were made by 16 teams in Japan. The model is composed of a cylinder and a torispherical head with a conical transition. The ... -
The Effect of Crack Length Unevenness on Stress Intensity Factors Due to Autofrettage in Thick-Walled Cylinders
(The American Society of Mechanical Engineers (ASME), 1997)The effect of crack length unevenness on the mode I stress intensity factors (SIFs) for large uniform arrays of radial cracks of unequal depth in fully or partially autofrettaged thick-walled ... -
An Investigation on the Properties of Underwater Shock Waves Generated in Underwater Explosions of High Explosives
