Singular Fields in Plane-Strain Penetration

Journal of Applied Mechanics, 1991
Local singular fields are investigated in the vicinity of the vertex of a sharp wedge that penetrates a viscous solid. Material behavior is modeled by the usual powerlaw constitutive relation. Wall friction is accounted for by imposing friction factors along the walls of the wedge.

Optical in-plane strain field sensor

Applied Optics, 2002
A whole-field speckle strain sensor is presented. The speckle strain sensor allows the measurement of all three in-plane components of the strain field simultaneously without touching the surface of the sample. The strain fields are extracted from the in-plane motion of defocused laser speckles in a telecentric imaging system.

Imaging Strain Fields

2009
As we discussed in Chapter 24, bending of the lattice planes causes a change in the diffraction conditions and therefore a change in the contrast of the image. The presence of a lattice defect in the specimen causes the planes to bend close to the defect.

Finite-element study of strain field in strained-Si MOSFET

Micron, 2009
The strain field in the channel of a p-type metal-oxide-semiconductor field effect transistor fabricated by integrating Ge pre-amorphization implantation for source/drain regions is evaluated using a finite-element method combining with large angle convergent-beam electron diffraction (LACBED).

Direct strain tensor approximation for full‐field strain measurement methods

International Journal for Numerical Methods in Engineering, 2013
SUMMARYFull‐field strain measurement techniques are based on computing the spatial derivatives of numerical or functional approximations of the underlying displacement fields extracted from digital imaging methods. These methods implicitly assume that the medium satisfies the strain compatibility conditions, which are only true in the case of a ...

Strain tensor field in proteins

Journal of Molecular Graphics, 1996
The tensor fields of pressure strain imposed on protein molecules have been visualized by computer graphics and computational geometry. The pressure-induced deformations of lysozyme and myoglobin were analyzed by the present method, which regards each molecule as a patchwork of microscopic continuous bodies of Delaunay tetrahedra.

Engineering Monolayers With Strain Field

Materials, 2004
A binary monolayer on an elastic substrate may self-organize into ordered nanoscale patterns. Here we report a work of using a substrate strain field to guide the self-assembly process. The study shows that straining a substrate uniformly does not influence the pattern.

Field induced strains in antiferroelectrics

IEEE Symposium on Ultrasonics, 2002
Lead zirconate-based materials with a slight content of titanium undergo an antiferroelectric-ferroelectric phase transition when an electric field is applied. The strains accompanying this field-induced transition are gigantic in comparison with the strain change in the antiferroelectric or ferroelectric state.
