Can an increase in abutment screw length enable biomechanical advantages for implants with increased crown height space? [PDF]
J ProsthodontAbstract Purpose The purpose of this finite element analysis (FEA) study was to investigate how screw length and crown height affect the stresses generated in the implant‐abutment complex and alveolar bone for anterior single implants and whether the use of longer abutment screw would compensate for increased stresses originated from increased crown ...

Inverse problem of photoelastic fringe mapping using neural networks [PDF]
, 2007 This paper presents an enhanced technique for inverse analysis of photoelastic fringes using neural networks to determine the applied load. The technique may be useful in whole-field analysis of photoelastic images obtained due to external loading, which

Photoelastic residual stress measurement in nonaxisymmetric glass containers
EPJ Web of Conferences, 2010 Residual stresses in axisymmetric glass containers are mostly measured with integrated photoelasticity. However, many containers, e.g. cosmetic bottles and bottles of expensive alcoholic drinks, often have a non-axisymmetric form.

Evaluation of stress intensity factor of multiple inclined cracks under biaxial loading
Fracture and Structural Integrity, 2012 A finite rectangular plate of unit thickness with two inclined cracks (parallel and non parallel) under biaxial mixed mode condition are modelled using finite element method. The finite element method is used for determination of stress intensity factors

Electron-phonon interaction via Pekar mechanism in nanostructures [PDF]
, 2004 We consider an electron-acoustic phonon coupling mechanism associated with the dependence of crystal dielectric permittivity on the strain (the so-called Pekar mechanism) in nanostructures characterized by strong confining electric fields. The efficiency

Stick-Slip Dynamics in a Granular Material With Varying Grain Angularity
Frontiers in Physics, 2022 Experiments, simulations, and theoretical treatments of granular materials typically feature circular or elliptical grains. However, grains found in natural systems often have flat faces that introduce local rotational constraints; these rotational ...
