Parametric Instability of a Non-uniform Beam with Thermal Gradient on Pasternak Foundation [PDF]

, 1991
The dynamic instability behavior of a tapered cantilever beam on a Pasternak foundation under the action of a pulsating axial force and a steady, one-dimensional temparature gradient is studied.

Bending analysis of nano-sized beam-elastic substrate systems: Unification of the stress-driven nonlocal model and Winkler-Pasternak foundation model

Results in Engineering
Nano- and micro-scale beam–substrate assemblies are key components of sensors, actuators, and flexible electronics, yet their mechanical responses deviate from classical elasticity because intrinsic material length scales govern their behavior.

NONLINEAR VIBRATION OF A BEAM SUBJECTED TO MECHANICAL IMPACT AND WINKLER-PASTERNAK FOUNDATION [PDF]

The simultaneous effects of mechanical impact and Winkler-Pasternak foundation on the dynamic response of an Euler-Bernoulli beam are studied. By means of the Galerkin-Bubnov procedure, the governing equation with partial derivatives is reduced to an ...

Predictive Model for Deformation of Adjacent Pipelines Caused by Tunnel Boring in Twin-Lane Tunnels in Soft Ground Layers

Applied Sciences
To create a discretized prediction model for the deformation of an adjacent pipeline, the pipeline structure is discretized, the differential equations governing the longitudinal deformation of the pipeline are inferred, and the displacement expressions ...

DQ thermal buckling analysis of embedded curved carbon nanotubes based on nonlocal elasticity theory

Latin American Journal of Solids and Structures
To investigate the thermal buckling of curved carbon nanotubes (CCNTs) embedded in an elastic medium, nonlocal elasticity theory is employed in combination with the theory of thin curved beams.

Free vibration analysis of graphene-reinforced FGM microplates under different boundary conditions

Tạp chí Khoa học và Công nghệ
This paper analyzes the free vibration of micro-sized plates placed on the Winkler-Pasternak elastic foundation. The microplate is made from functionally graded material (FGM) and reinforced with graphene nanoplatelets (GPLs).
