Vibration Characteristics of Planar Curved Beams on Elastic Pasternak Foundations
, 2021 —The objective of this study is to investigate the forced vibration analysis of a planar curved beam lying on elastic foundation by using the mixed finite element method. The finite element formulation is based on the Timoshenko beam theory. In order to solve the problems in frequency domain, the element matrices of two nodded curvilinear elements are ...

A new analytic symplectic elasticityapproach for beams resting on Pasternak elastic foundations [PDF]
Journal of Mechanics of Materials and Structures, 2010 Analytic solutions describing the stresses and displacements of beams on a Pasternak elastic foundation are presented using a symplectic method based on classical two-dimensional elasticity theory. Hamilton’s principle with a Legendre transformation is employed to derive the Hamiltonian dual equation, and separation of variables reduces the dual ...
