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.

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.
