On the stability loss for an euler beam resting on a tensionless pasternak foundation [PDF]

, 2013
In the present work, the tensionless contact problem of an Euler\u2013Bernoulli beam of finite length resting on a two-parameter Pasternak-type foundation is investigated.

Comparative dynamic analysis of axially loaded beams on modified Vlasov foundation [PDF]

, 2016
Vibration analysis of the beams on elastic foundation has gained the great interest of many researchers. In the literature, there are many studies that focus on the free vibration analysis of the beams on one or two parameter elastic foundations.

Effect of Orthotropic Variable Foundations and Unconventional Support Conditions on Nonlinear Hygrothermoelectric Vibration of Porous Multidirectional Piezoelectric Functionally Graded Nonuniform Plate

International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 535-563, September 2025.
ABSTRACT This article investigates the nonlinear vibration behavior of porous multidirectional piezoelectric functionally graded nonuniform (PFGN) plates resting on orthotropic variable elastic foundations and subjected to hygrothermal loading. The sigmoidal law is employed to define the multidirectional gradation properties, incorporating porosity ...

Analysis of the contact problem functionally graded layer placed on a Pasternak foundation

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 8, August 2025.
Abstract This paper uses analytical and numerical methods to investigate the frictionless receding contact problem of two layers, one functionally graded (FG), loaded by a circular rigid block and resting on a Pasternak foundation. The upper layer loaded by the circular punch has homogeneous properties and contains a single shear modulus, while the ...

A new sinusoidal shear deformation theory for bending, buckling, and vibration of functionally graded plates [PDF]

, 2012
A new sinusoidal shear deformation theory is developed for bending, buckling, and vibration of functionally graded plates. The theory accounts for sinusoidal distribution of transverse shear stress, and satisfies the free transverse shear stress ...

Updated consumer risk assessment of fluoride in food and drinking water including the contribution from other sources of oral exposure

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract This updated risk assessment evaluated evidence on potential adverse health effects of fluoride related to all sources of oral exposure as mandated by the European Commission. Fluoride benefit assessment was not included. Effects on the central nervous system, thyroid and bone were prioritised.
