Radial strain at radius r i. Concrete Poisson coefficient.
The equivalent strain at a radius of 3 mm was about 55, which is calculated using Eq. (1), where r is the radius of interest, n the number of rotations and h the sample thickness: (1) ε eq = 2 π rn h 3 Further details concerning the whole HPT process and the heating/cooling setup used are described elsewhere [1,12,13].
A significant dependence of the peak average stress and failure strain on notch radius is observed.
The residual stress of the PET substrate with TiO2 film significantly increased with increasing strain, decreasing the radius of curvature.
At that the surface modification is controlled by numerous parameters like loading force, friction coefficient, tool's tip radius, strain rate, and number of tool passes.
A performance-based design flowchart is also provided along with a design example for determining the pre-strain and the radius of cross section of wires in the SMA wire-based rubber bearings.
Under small deformations, the isochoric condition also requires dilation of the radius, radial strain Sr, to be related to the axial strain Sx by Sr = −Sx/2.
A radius related strain distribution is proposed to get analytical solutions for the excess pore water pressure and settlement.
Such optical techniques have been applied to measure physical parameters such as curvature radius, displacement, strain, surface profile and refractive index.
In this paper, we critically evaluate the validity of the different definitions of both the indentation strain and the contact radius by applying the protocols on datasets generated from a finite element simulation of spherical indentation.
