An Extension of the Pasternak Foundation Concept
Soils and Foundations, 1985 ABSTRACT The Pasternak Foundation concept, a refinement of the Winkler Foundation theory, is briefly stated and its shortcomings pointed out. The [concept is extended to take into account material nonlinearity and body forces using an analytical approach.

Quantification of cracks in beams on the Pasternak foundation using Haar wavelets and machine learning [PDF]
Proceedings of the Estonian Academy of Sciences, 2022 The inverse problem of crack identification, localisation and severity quantification is addressed in this article. The open cracks are simulated numerically in a homogeneous EulerâBernoulli beam. The beam rests on the Pasternak foundation.

Behaviors of pile-column piers based on modified pasternak foundation model
Yantu gongcheng xuebao, 2022 The analysis of behaviors of pile-column piers in layered soils under inclined loads is extremely complicated. An improved Pasternak foundation reaction model considering the plastic yield characteristics of soils is proposed.

Hydroelastic oscillation of a plate resting on Pasternak foundation [PDF]
Vibroengineering Procedia, 2017 The bending oscillations of the plate, resting in Pasternak foundation and interacting with a vibrating stamp through a thin layer of viscous incompressible liquid, are investigated. On the basis of hydroelasticity problem solution, the laws of the plate deflections and pressure in the liquid are found.
