On the basis of a decomposition method of static indeterminacy, equations of simplified deflection curves are obtained and, accordingly, the actual gage length is confirmed. For corporate researchers we can also follow up directly with your R&D manager, or the information Notice, Smithsonian Terms of The computer you are using is not registered by an institution with a subscription to this article. Specimens with larger l o and ρ present more obvious measurement errors for Young's modulus, but the effect of ΔT is not significant. By continuing to use this site you agree to our use of cookies. Furthermore, the quantitative effects of ideal gage length l o, temperature change ∆T and the density ρ of the specimen on the modulus difference and modulus ratio are calculated. You will only need to do this once. The Young Modulus is also known as Young's Modulus or the elastic modulus or tensile modulus.. You will only need to do this once. No, Zhichao Ma et al 2016 Meas. Zhichao Ma1,2, Hongwei Zhao1,3 and Luquan Ren2, Published 27 April 2016 • Young's modulus measured by uniaxial tensile testing is affected by many inevitable factors, such as misalignment of the tensile axis [6–9], initial residual stress and clamping position . By comparing the effects of uniaxial tensile load on the change of the deflection curve with gravity, the relation between the actual and directly measured tensile Young's modulus is obtained.

Specimens with larger lo and ρ present more obvious measurement errors for Young's modulus, but the effect of ΔT is not significant. Method 5. Accepted 31 March 2016 It consists of two equal length wires that are attached to a rigid support. Most miniature in situ tensile devices compatible with scanning/transmission electron microscopes or optical microscopes adopt a horizontal layout. In order to analyze and calculate the measurement error of the tensile Young's modulus, the effects of gravity and temperature changes, which would respectively lead to and intensify the bending deformation of thin specimens, are considered as influencing factors. © 2016 IOP Publishing Ltd To find out more, see our, Browse more than 70 science journal titles, Read the very best research published in IOP journals, Read open access proceedings from science conferences worldwide, Effects of 2D misalignment on tensile results and corresponding correction methods to obtain the true stress–strain curve, Decomposition method based on a modified Arcan fixture and its application in an, A mechanical system for tensile testing of supported films at the nanoscale, Correction method for mechanical performance testing instrument with tension–torsion coupling loading, Mechanical characterization of thermal SiO, Modular correction method of bending elastic modulus based on sliding behavior of contact point. The Young Modulus is named after Thomas Young (1773 to 1829) who was a British polymath, contributing to our understanding of optics, physiology, and Egyptology, among other fields.
