RISNonlinear Stability of the Generalized Eady Model
Publisher: American Meteorological Society
Abstract: Linear and nonlinear stability theorems for the generalized Eady model are obtained by the normal-mode method and the energy?Casimir method, respectively. The nonlinear stability criterion is optimal in the following sense: ...
Effects of Stress Ratio and Banded Microstructure on Fatigue Crack Growth Behavior of HRB400 Steel Bar
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effects of stress ratio and microstructure on the fatigue crack growth (FCG) behavior of HRB4 steel bars widely used in concrete bridges. A constant stress–controlled FCG test with different ...
An Equivalent Creep Crack Growth Model for Probabilistic Life Prediction of Plastic Pipe Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Life prediction in energy infrastructure such as gas pipelines is important to maintain the integrity of such systems. This paper explores a life prediction model for polyethylene materials in natural gas distribution ...
Towards Integrated Design and Operation of Complex Engineering Systems With Predictive Modeling: State-of-the-Art and Challenges
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Growing trends towards increased complexity and prolonged useful lives of engineering systems present challenges for system designers in accounting for the impacts of post-design activities (e.g., manufacturing, condition ...
Microstructure Representation and Reconstruction of Heterogeneous Materials Via Deep Belief Network for Computational Material Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Integrated Computational Materials Engineering (ICME) aims to accelerate optimal design of complex material systems by integrating material science and design automation. For tractable ICME, it is required that (1) a ...
