If you have a user account, you will need to reset your password the next time you login. 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. Form and we will follow up with your librarian or Institution on your behalf. 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 . To understand how Searle’s apparatus is used to determine Young’s modulus of elasticity of the material of a given wire, read the below experiment.

You will only need to do this once.
Most miniature in situ tensile devices compatible with scanning/transmission electron microscopes or optical microscopes adopt a horizontal layout.

No, Zhichao Ma et al 2016 Meas. 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.

Measurement Science and Technology, Specimens with larger l o and ρ present more obvious measurement errors for Young’s modulus, but the effect of ∆T is not significant. 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.
