Measurement of mechanical properties at the bottom of a granular pack by wavelength-scanning interferometry
thesis
posted on 2018-07-20, 09:07 authored by Yanzhou ZhouGranular materials are conglomerations of discrete macroscopic particles. These
deceptively simple materials, however, are very different from the ordinary solids,
liquids and gases we know from physics textbooks.
One method to understand the static mechanical properties of granular media is to
study the contact forces and displacements particle by particle, and generalize the
statistical results for the whole pack theoretically and experimentally. Unfortunately,
there are a range of interpretations and little experimental data to compare to and
subsequently we have made relatively little progress in understanding force
transmission in granular media since the 1960s.
Progress requires experimental methods that are accurate down to the single particle
level. In this thesis, we introduce a new reflective scanning-wavelength Fizeau
interferometer which achieves this and has the advantages of a wide range and is
applicable to three dimensional systems. [Continues.]
