Modeling, vibration, and stability of elastically tailored composite thin-walled beams carrying a spinning tip rotor
(Acoustical Society of America, 2001-08-01)
The problems of the mathematical modeling, eigenvibration, and stability of cantilevered thin-walled beams carrying a spinning rotor at its tip are investigated. The structure modeled as a thin-walled beam encompasses ...
Implication of conservative and gyroscopic forces on vibration and stability of an elastically tailored rotating shaft modeled as a composite thin-walled beam
(Acoustical Society of America, 2001-03-01)
Problems related with the implications of conservative and gyroscopic forces on vibration and the stability of a circular cylindrical shaft modeled as a thin-walled composite beam and spinning with constant angular speed ...
Network structure and thermal stability study of high temperature seal glass
(American Institute of Physics, 2008-10-01)
High temperature seal glass has stringent requirement on glass thermal stability, which is dictated by glass network structures. In this study, a SrO-La2O3-Al2O3-B2O3-SiO2 based glass system was studied using nuclear ...
A Framework for Building Open Digital Libraries
(Corporation for National Research Initiatives, 2001-12-01)
Digital libraries (DLs) have traditionally been positioned at the intersection of library science, computer science, and networked information systems. The different underlying philosophies of these three fields has had ...
Breakdown of structural models for vibrations of single-wall zigzag carbon nanotubes
(American Institute of Physics, 2009-09-15)
Free vibrations of zigzag single-wall carbon nanotubes (SWCNTs) of aspect ratio (length/diameter) similar to 6 and with ends traction-free have been studied using molecular mechanics (MM) simulations with the MM3 potential. ...
Using transient shear rheology to determine material parameters in fiber suspension theory
(AIP Publishing, 2009-05-01)
Fiber suspension theory model parameters for use in the simulation of fiber orientation in complex flows are, in general, either calculated from theory or fit to experimentally determined fiber orientation generated in ...
Role of Nanoscale Precipitates on the Enhanced Magnetostriction of Heat-Treated Galfenol (Fe1-xGax) Alloys
(American Physical Society, 2009-03-27)
We report neutron diffuse scattering measurements on highly magnetostrictive Fe1-xGax alloys (0.14 < x < 0.20) with different thermal treatments. This diffuse scattering scales with magnetostriction and exhibits asymmetric ...
An XML Log Standard and Tool for Digital Library Logging Analysis
(2002-09-01)
Log analysis can be a primary source of knowledge about how digital library patrons actually use DL systems and services and how systems behave while trying to support user information seeking activities. Log recording and ...
MARIAN: Flexible Interoperability for Federated Digital Libraries
(2001)
Federated digital libraries are composed of distributed autonomous (heterogeneous) information services but provide users with a transparent, integrated view of collected information respecting different information sources' ...
Bias-field effect on the temperature anomalies of dielectric permittivity in PbMg1/3Nb2/3O3-PbTiO3 single crystals
(American Physical Society, 2005-11-16)
In contrast to ordinary ferroelectrics where the temperature T-m of the permittivity maximum monotonically increases with bias field E in (1-x)PbMg1/3Nb2/3O3-(x)PbTiO3 (0 <= x <= 0.35) single crystals, T-m was found to ...
