RISA Strain Gradient Model for Fracture Prediction in Brittle Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a new model to predict the fracture in brittle materials from a geometrical weakness presenting an arbitrary stress concentration. The main idea is to combine the ...
Transport Coordinate (TC) Method for the Dynamics of Multiple Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we propose a new idea of tracking material interface. Since the regions filled with different materials at the initial time are merely transported by the velocity field, the ...
Global Linear Stability of the Two-Dimensional Shallow-Water Equations: An Application of the Distributive Theorem of Roots for Polynomials on the Unit Circle
Publisher: American Meteorological Society
Abstract: This paper deals with the numerical stability of the linearized shallow-water dynamic and thermodynamic system using centered spatial differencing and leapfrog time differencing. The nonlinear version of the equations is ...
IntelliGIS: Tool for Representing and Reasoning Spatial Knowledge
Publisher: American Society of Civil Engineers
Abstract: This paper presents a method for the representation and reasoning of spatial knowledge. Spatial knowledge is important to decision making in many transportation applications that involve human judgment and understanding ...
A Nowcast/Forecast System for Coastal Ocean Circulation Using Simple Nudging Data Assimilation
Publisher: American Meteorological Society
Abstract: This study describes the establishment of a Nowcast/Forecast System for Coastal Ocean Circulation (NFS-COC), which was run operationally on a daily basis to provide users ocean surface currents and sea levels that vary ...
Formation of an Azores Current Due to Mediterranean Overflow in a Modeling Study of the North Atlantic
Publisher: American Meteorological Society
Abstract: A mechanism for the formation of the Azores Current is proposed. On the basis of observations and model results, it is argued that the primary cause of the Azores Current is the water mass transformation associated with ...
Attribution of the Subsurface Temperature Change in the Southern Hemisphere
Publisher: American Meteorological Society
Abstract: The Southern Hemisphere temperature has experienced obvious changes with great spatial differences over the past several decades. Most regions show extreme warming, especially those located at 35°–55°S. In contrast, ...
A Hybrid Approach Using Design of Experiment and Artificial Neural Network in a Camless Heavy-Duty Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Increasingly stricter emission regulations and fleet CO2 targets drive the engine development toward clean combustion and high efficiency. To achieve this goal, planning and conducting experiments in a time- and cost-effective ...
Interannual Variations and Prediction of Spring Precipitation over China
Publisher: American Meteorological Society
Abstract: AbstractThe interannual variations and the prediction of the leading two empirical orthogonal function (EOF) modes of spring (April?May) precipitation over China for the period from 1951 to 2014 are investigated using both ...
Applicability of CMIP5 and CMIP6 Models in China: Reproducibility of Historical Simulation and Uncertainty of Future Projection
