Finite Element Based Full-Life Cyclic Stress Analysis of 316 Grade Nuclear Reactor Stainless Steel Under Constant, Variable, and Random Fatigue Loading
(The American Society of Mechanical Engineers (ASME), 2018)Although S∼N curve-based approaches are widely followed for fatigue evaluation of nuclear reactor components and other safety critical structural systems, there is a chance of large uncertainty in estimated fatigue lives. ... -
The Sensitivity to the Lode Parameter in Ductile Failure of Tubular Steel Grades
(The American Society of Mechanical Engineers (ASME), 2018)Ductile failure in steels is highly controlled by the stress state, characterized by the stress triaxiality (T) and the Lode parameter (L). The ASME Boiler and Pressure Vessel Code requires pressure vessels to be designed ... -
The Drag Crisis and Thermowell Design
(The American Society of Mechanical Engineers (ASME), 2018)Documented thermowell failures designed to PTC 19.3TW and earlier, when evaluated with the drag crisis invoked, reveals the potential for enhanced reliability of the current standard in reducing the risk of failure. The ... -
A Cyclic-Plasticity-Based Mechanistic Approach for Fatigue Evaluation of 316 Stainless Steel Under Arbitrary Loading
(The American Society of Mechanical Engineers (ASME), 2018)In this paper, a cyclic-plasticity-based fully mechanistic fatigue modeling approach is presented. This is based on time-dependent stress–strain evolution of the material over the entire fatigue life rather than just based ... -
Failure Modes of American Petroleum Institute 12F Tanks With a Rectangular Cleanout and Stepped Shell Design
