Abstract In this study, a comprehensive analytical framework is developed to investigate the free vibration behavior of double‐walled carbon nanotubes (DWCNTs) resting on an elastic foundation, based on Eringen's nonlocal elasticity theory. The DWCNTs are modeled as two coupled Euler–Bernoulli (EB) beams, explicitly incorporating intertube van der ...

In pulsed CO2 electroreduction, the electrolyte cation identity and size determine the multicarbon product formation over oxide‐derived Cu nanocatalysts. In situ X‐ray studies revealed enhanced dissolution and increased Cu lattice parameter adaptation linked to enhanced ethanol and suppressed hydrogen formation, suggesting an increased dynamicity of ...

Uncertainty Quantification in Modeling of Steel Structures using Timoshenko Beam [PDF]
This paper quantifies the uncertainty emanated from modeling steel structures using a Timoshenko beam. Using continuous beams to model building structures is a conventional approach in structural dynamic analyses.

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

Size effects on free vibration of heterogeneous beams
In this paper the influence of microstructure on the free vibration of geometrically similar heterogeneous beams with free-free boundary conditions was numerically investigated by detailed finite element analysis (FEA) to identify and quantify any effect

A piecewise continuous Timoshenko beam model for the dynamic analysis of tapered beam-like structures [PDF]
Distributed parameter modeling offers a viable alternative to the finite element approach for modeling large flexible space structures. The introduction of the transfer matrix method into the continuum modeling process provides a very useful tool to ...

Effective Material Stiffness in Curved Actuators
A new actuator effective material stiffness measurement method is created. It produces a new metric called shape actuation modulus with the potential to help design actuators. This method shows that the smaller the curvature of hinge‐shaped actuators, the stiffer they are.

Is it possible to assign physical meaning to field theory with higher derivatives?
To overcome the difficulties with the energy indefiniteness in field theories with higher derivatives, it is supposed to use the mechanical analogy, the Timoshenko theory of the transverse flexural vibrations of beams or rods well known in mechanical ...
