Nondestructive Evaluation of Solids Based on Deformation Wave Theory
Applied Sciences, 2020 The application of a recent field theory of deformation and fracture to nondestructive testing (NDT) is discussed. Based on the principle known as the symmetry of physical laws, the present field theory formulates all stages of deformation including the ...

Optical strain measuring techniques for high temperature tensile testing [PDF]
A number of optical techniques used for the analysis of in-plane displacements or strains are reviewed. The application would be for the high temperature, approximately 1430 C (2600 F), tensile testing of ceramic composites in an oxidizing atmosphere ...

Towards optical intensity interferometry for high angular resolution stellar astrophysics [PDF]
, 2012 Most neighboring stars are still detected as point sources and are beyond the angular resolution reach of current observatories. Methods to improve our understanding of stars at high angular resolution are investigated.

Light-in-flight digital holography display [PDF]
, 1994 We present a digital speckle-pattern interferometric setup that can be operated at TV frame rates (30 ms) to display the locus of the points at which the optical-path difference between the reference and object beams is within the coherence length ...

Warpage in Material Extrusion Additive Manufacturing of Amorphous and Semicrystalline Polymers
Macromolecular Materials and Engineering, Volume 310, Issue 12, December 2025.Material Extrusion Additive Manufacturing (MEAM) enables the fabrication of complex parts, but faces the challenge of warpage due to thermal stresses and phase transitions. This review examines the warpage mechanism, the role of processing conditions, material properties, and part geometry.

Twisted superfluids in moving frame
, 2020 {Helical waveguide filled by superfluid is shown to transform the linear displacements of reference frame $\vec V$ into rotations of atomic ensemble and vise versa rotations of reference frame $\vec \Omega_{\oplus}$ are the cause of linear displacements ...
