RISComparison of Existing Methods for Characterizing Bi-Linear Natural Ankle Quasi-Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural ankle quasi-stiffness (NAS) is a mechanical property of the ankle joint during dynamic motion. NAS has been historically calculated as the average slope (linear regression) of the net ankle moment versus ankle angle ...
On the Effective Viscosity Expression for Modeling Squeeze Film Damping at Low Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While at high pressure, the classical Navier–Stokes equation is suitable for modeling squeezefilm damping, at low pressure, it needs some modification in order to consider fluid rarefaction. According to a common approach, ...
Equivalent One-Dimensional System for Analysis of Taper Leaf Springs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper an equivalent one-dimensional system for taper leaf springs (similar to those used in vehicle suspension systems) is developed so that results obtained from it are in good agreement ...
Experimental Investigation of FRP-Concrete Debonding under Cyclic Actions
Publisher: American Society of Civil Engineers
Abstract: The effectiveness of externally bonded fiber-reinforced polymer (FRP) laminates for strengthening existing reinforced concrete (RC) structures is strictly related to the bond of the FRP reinforcement to the concrete ...
Shear Connection Nonlinearity and Deflections of Steel–Concrete Composite Beams: A Simplified Method
Publisher: American Society of Civil Engineers
Abstract: In steel and concrete composite beams, the incomplete interaction between steel profile and concrete slab leads to an appreciable increase of the beam deflections with respect to full interaction behavior. Moreover, the ...
In-Cylinder Flow Computational Fluid Dynamics Analysis of a Four-Valve Spark Ignition Engine: Comparison Between Steady and Dynamic Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical and experimental techniques were applied in order to study the in-cylinder flow field in a commercial four-valve per cylinder spark ignition engine. Investigation was aimed at analyzing ...
Direct versus Indirect Method for Identifying FRP-to-Concrete Interface Relationships
Publisher: American Society of Civil Engineers
Abstract: Several proposals have been carried out for modeling a fiber-reinforced-polymer (FRP)-to-concrete interface whose behavior is not completely described by fracture energy value, which could often be derived in closed form. ...
Analysis of the Ross Ice Shelf Airstream Forcing Mechanisms Using Self-Organizing Maps
Publisher: American Meteorological Society
Abstract: he Ross Ice Shelf airstream (RAS), a prominent transport mechanism of cold, continental air to the north, is the most common wind pattern over the Ross Ice Shelf, Antarctica. The forcing mechanisms of the RAS include ...
Identification of Surface Wind Patterns over the Ross Ice Shelf, Antarctica, Using Self-Organizing Maps
Publisher: American Meteorological Society
Abstract: he interaction of synoptic and mesoscale circulations with the steep topography surrounding the Ross Ice Shelf, Antarctica, greatly influences the wind patterns in the region of the Ross Ice Shelf. The topography provides ...
Non-Newtonian Squeeze Film Between Two Plane Annuli
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis is presented for the laminar squeezing flow of an incompressible power-law fluid between parallel plane annuli. The results obtained are based on the thin-film approximation, and ...
