RISInelastic Contact Behavior of Crystalline Asperities in rf MEMS Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microelectromechanical systems (MEMS), particularly those with radio frequency (rf) applications, have demonstrated significantly better performance over current electromechanical and solid-state ...
Modeling of Lath Martensitic Microstructures and Failure Evolution in Steel Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multiple-slip dislocation-density-based crystalline formulation, specialized finite-element formulations, and Voronoi tessellations adapted to martensitic orientations were used to investigate ...
Prediction of Grain-Boundary Interfacial Mechanisms in Polycrystalline Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multiple slip dislocation-density based crystalline formulation has been coupled to a kinematically based scheme that accounts for grain-boundary (GB) interfacial interactions with dislocation ...
Integrated Experimental, Atomistic, and Microstructurally Based Finite Element Investigation of the Dynamic Compressive Behavior of 2139 Aluminum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this study was to identify the microstructural mechanisms related to the high strength and ductile behavior of 2139-Al, and how dynamic conditions would affect the overall ...
