The Generalized Finite Element Method (GFEM) can be viewed as an extension of the Finite Element Method (FEM) where the approximation space is enriched by shape functions appropriately chosen. Many ...

This paper presents the effect of nonlocal scaling parameter on the coupled i.e., axial, flexural, shear and contraction, wave propagation in single-walled carbon nanotubes (SWCNTs). The axial and ...

Negative stiffness (NS) structures have obvious advantages in attenuating low-frequency vibration. Although most existing NS structures exhibit good damping effects, their stability is poor, limiting ...

In automotive parts, medical implants, running shoes, and hiking backpacks, we’re seeing more and more 3D-printed components featuring lattice or honeycomb patterns. You might think these lattice ...

Caltech scientists are developing laser-driven lightsails that could push spacecraft beyond our solar system. Their research focuses on understanding how ultrathin materials respond to radiation ...

Levodopa is the most effective drug for controlling Parkinson's disease symptoms. Deep brain stimulation surgery may help people who have tried all medication options. Exercise and good nutrition help ...

The universe shouldn’t be here. Everything scientists know about particle physics, summed up in a theory called the Standard Model, suggests that the big bang should have created equal quantities of ...

Abstract: We present a new mathematical model for a vibrating ring gyroscope (VRG) in the presence of imperfections, namely, structural defects and material anisotropy. As a novelty, we calculate the ...
