A Determination Of The Modulus Of Elasticity For Small Loads, Charles P. Weston Jan 1899

A Determination Of The Modulus Of Elasticity For Small Loads, Charles P. Weston

Physics and Astronomy Faculty Scholarship

"At the suggestion of Professor James S. Stevens, and under his supervision, I undertook to apply interference methods of measurement to an experimental determination of Young's modulus for copper, brass, and steel. The metals were in the form of bars, 66 cm x 1 cm x 0.5 cm (approximate dimensions). The general method followed was the so-called "method of flexure" in which a bar, supported at each end on knife edges, if deflected by a weight applied at the center,


An Application Of Interference Mmthods To A Study Of The Changes Produced In Metals By Magnetization, J. S. Stevens Jan 1898

An Application Of Interference Mmthods To A Study Of The Changes Produced In Metals By Magnetization, J. S. Stevens

Physics and Astronomy Faculty Scholarship

Problems which have for their object a study of the changes produced in metals when magnetized have, during the past fifty years, received attention from physicists. It is thought that if a thorough investigation of the subject could be made, much light would be thrown upon the phenomenon of magnetization, and even the theory of the constitution of matter. Historical notes relating to this problem may be found in the Physical Review, Vol. III, No. 15, and Vol. V., No. 5. The results of various investigators agree fairly well as to the maximum elongation of a rod or wire when …

Self‐Consistent Electronic Structure Of Disordered Fe0.65ni0.35, Duane D. Johnson, F. J. Pinski, G. M. Stocks Dec 984

Self‐Consistent Electronic Structure Of Disordered Fe0.65ni0.35, Duane D. Johnson, F. J. Pinski, G. M. Stocks

Duane D. Johnson

We present the results of the first a b i n i t i o calculation of the electronic structure of the disordered alloy Fe0.65Ni0.35. The calculation is based on the multiple‐scattering coherent‐potential approach (KKR‐CPA) and is fully self‐consistent and spin polarized. Magnetic effects are included within local‐spin‐density functional theory using the exchange‐correlation function of Vosko–Wilk–Nusair. The most striking feature of the calculation is that electrons of different spins experience different degrees of disorder. The minority spin electrons see a very large disorder, whereas the majority spin electrons see little disorder. Consequently, the minority spin density of states is smooth …


Studying Properties Of Xenon Doped Argon And Developing Optical Simulation Techniques For The Legend Collaboration, A Neutrinoless Double Beta Decay Experiment, Neil Christopher Mcfadden Dr Feb 202

Studying Properties Of Xenon Doped Argon And Developing Optical Simulation Techniques For The Legend Collaboration, A Neutrinoless Double Beta Decay Experiment, Neil Christopher Mcfadden Dr

Physics & Astronomy ETDs

Neutrinoless double beta decay is a hypothesized lepton-number-violating process in which two neutrons decay to two protons, producing two electrons but no electron antineutrinos. The LEGEND collaboration will search for this decay in 76Ge. To improve the argon active veto for LEGEND-1000, xenon doped argon was explored as an alternative active volume. Simulations using argon doped with 10 ppm xenon and pure liquid argon were used to predict the light yield from cosmic muons in a 100 liter cryogenic vessel. The simulations predicted that xenon doping would yield 1.83+/-0.02 more light, while an increase of 1.81+/-0.05 was measured. From …
