Nonlinear Vibration of Multilayer Nonhomogeneous Moderately-Thick Cylindrical Shells on Three-Parameter Nonlinear Foundations [PDF]

Journal of Applied and Computational Mechanics
This study focuses on the analysis of the nonlinear vibration behavior of nonhomogenous isotropic (NHI) multilayered cylindrical shells resting on three-parameter nonlinear elastic foundations (Winkler-Pasternak type) within a theoretical framework based

Effects of Aging, Estimated Fitness, and Cerebrovascular Status on White Matter Microstructural Health

Human Brain Mapping, Volume 46, Issue 5, 01 April 2025.
White matter (WM) health declines with age and improves with estimated fitness. However, the effects of age and estimated fitness do not completely overlap spatially. Cerebrovascular health mediates the relationships of WM health with both age and estimated fitness. Males show steeper declines in WM health than females.

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.

Modal analysis of plates resting on elastic foundation based on the first-order shear deformation theory and finite element method

Vietnam Journal of Mechanics
This paper investigates the free vibration characteristics of plate structures supported by a Pasternak elastic foundation, utilizing the first-order shear deformation theory (FSDT). FSDT simplifies the plate theory by considering only first-order shear
