Elastic thermal deformations in EOS units measuring and simulation
2017 Eighteenth International Vacuum Electronics Conference (IVEC), 2017This paper presents the results of the thermal movement measurements of cathode-heating unit (CHU) details for a powerful C-band multi-beam klystron. There are also the numerical simulation results of the CHU, that shows the good agreement between the experimental and the calculated data.

Thermally Twistable, Photobendable, Elastically Deformable, and Self‐Healable Soft Crystals
Angewandte Chemie, 2018AbstractThe first example of a smart crystalline material, the 2:1 cocrystal of probenecid and 4,4′‐azopyridine, which responds reversibly to multiple external stimuli (heat, UV light, and mechanical pressure) by twisting, bending, and elastic deformation without fracture is reported.

The object of the paper is to examine the role of anisotropicity in a visco-elastic plate subjected to an uneven temperature distribution. An expression for deflection of the particle at the middle section of a rectangular plate is found analytically.

Prediction of the Deformation in Stereolithography Products Based on Elastic Thermal Shrinkage
Polymer-Plastics Technology and Engineering, 1998Abstract Deformation of some specimens produced by a stereolithography system was studied experimentally and numerically. Three steps in the rapid prototyping process (part building, part removal, and postcure) imposed significant effects on dimensional accuracy. Dimensions of the specimens were measured after each step. Distortion during part building

Elastic-plastic thermal stresses and deformation of short-fibre composites
Journal of Materials Science, 1994A micromechanics model is proposed to analyse residual stresses and deformations that develop in short-fibre composites upon an applied uniform temperature change. The model is based on Eshelby's equivalent inclusion method and treats the interaction among fibres at finite volume fractions through the Mori-Tanaka mean field theory. The model treats the

Quasi‐Classical Trajectory of Thermal Neutrons in Elastically Deformed Crystals
physica status solidi (b), 1989AbstractThe propagation of thermal neutrons through distorted crystals is reconsidered on the basis of an adiabatic quantum mechanical approach which enables one to derive quasi‐classical trajectories of neutrons for an arbitrary elastic deformation of a crystal. It is shown that the quasi‐classical concept is generally applicable even in the case when

Deformation Due to Mechanical and Thermal Sources in Magneto‐Micropolar Elastic Medium
Multidiscipline Modeling in Materials and Structures, 2007The present investigation is concerned with a two‐dimensional problem in electromagnetic micropolar elasticity for a half‐space whose surface is subjected to mechanical or thermal source in the presence of a transverse magnetic field. Laplace and Fourier transform technique is used to solve the problem.

Analysis of thermal stress and deformation in elastically bonded optics
SPIE Proceedings, 2007This paper discusses analytical equations and finite-element models for thermal stresses and deformations caused by continuous edge, three-point and face elastomeric bonds. Analytical equations for the athermalized edge bond thickness are derived where possible and verified by finite-element solutions.

Three Mirrors Aberrations Optical Transform Function with the Thermal Elastic Deformation
Applied Mechanics and Materials, 2011The field angle of TMA (three mirrors aberration) optical system is larger than coaxial optical system and more susceptible to the structure deformation. Thermal optical analysis is proposed for evaluating the optical MTF (module transform function). Temperature loads, such as X axial, Y axial and Z axial temperature gradients, are put on the optical ...
