In this paper we describe the construction of a laboratory-made apparatus for the dynamical thermomechanical analysis (D-TMA) based on an impulse excitation technique (IET) and estimate the uncertainty of the measurement of Young's modulus of an unfired ceramic sample. The sample was measured ...
is developed in order to reduce this set to Burgers' equation. Finally, formulae which describe the velocity of pressure shocks are derived. The analysis of these formulae along with associated measurements allows calculation of Young's modulus in the circumferential direction for corn stalks. ...

Young's modulus of nano-composite systems composed of unsaturated polyester and epoxy resins with alumina nanoparticles of different sizes has been experimentally estimated. The nanoparticles used were spherical alpha-Al 2O 3 having 30–40 and 200 nm in diameter. Young's modulus was estimated using...
Equations for calculating the Young's modulus and Poisson's ratio are derived, and using these, an experimental demonstration of this method is presented. The average values of the Young's modulus and Poisson's ratio for the device layer commercially sourced silicon on a silicon-on-insulator (...

The Young’s Modulus (E) and the Poisson’s ratio(ν) were used to characterize the deformation behaviour in the elastic regime. The values of both these constants were optimised using iFEM. Since DIC is a non-contact strain measurement method which directly acquires the deflection from the sp...
