Lattice dynamics and phonon softening in Ni-Mn-Al Heusler alloys [PDF]

open access: yes, 2006
Inelastic and elastic neutron scattering have been used to study a single crystal of the Ni$_{54}$Mn$_{23}$Al$_{23}$ Heusler alloy over a broad temperature range.

Determining the constitutive behavior of nonlinear visco-elastic-plastic PMMA thin films using nanoindentation and finite element simulation

open access: yesMaterials & Design, 2021
Understanding the nonlinear visco-elastic-plastic behavior and properties of PMMA thin films during nanoindentation is helpful for predicting the plastic deformation of thermoplastic polymer products during manufacture and evaluating stress to predict ...

X-ray residual stress measurements on cold-drawn steel wire [PDF]

open access: yes, 1982
The interplanar spacing d{hkl} versus sin2 ψ distributions were measured for the 211, 310, 220 and 200 reflections from severely cold-drawn 0.7% C steel wire with a diameter of 0.25 mm. From the shape of the curves it was concluded that, as well as a 110

High-accuracy compliance correction for nonlinear mechanical testing: Improving Small Punch Test characterization

open access: yesNuclear Materials and Energy, 2021
Small punch test, SPT, of metallic materials is a very convenient mechanical test since it requires a small volume of material. However, SPT data from different laboratories suffer from large scatter, mainly due to the different experimental set-ups ...

Environmental bias and elastic curves on surfaces

open access: yes, 2014
The behavior of an elastic curve bound to a surface will reflect the geometry of its environment. This may occur in an obvious way: the curve may deform freely along directions tangent to the surface, but not along the surface normal.

Magnetomechanical effects in textured polycrystalline Tb76Dy24 [PDF]

open access: yes, 2000
Uniaxial stress-strain measurements were performed on polycrystalline Tb76Dy24 alloys which exhibit "giant magnetostriction" at cryogenic temperatures.

Finite indentation of highly curved elastic shells [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
Experimentally measuring the elastic properties of thin biological surfaces is non-trivial, particularly when they are curved. One technique that may be used is the indentation of a thin sheet of material by a rigid indenter, while measuring the applied force and displacement.

Elastic Analysis of Irregularly or Sparsely Sampled Curves

open access: yesBiometrics, 2022
Abstract We provide statistical analysis methods for samples of curves in two or more dimensions, where the image, but not the parameterization of the curves, is of interest and suitable alignment/registration is thus necessary. Examples are handwritten letters, movement paths, or object outlines.
