Mechanical Properties Analysis of Bilayer Euler-Bernoulli Beams Based on Elasticity Theory [PDF]
International Journal of Engineering, 2020 This paper analyzes the effects of structures and loads on the static bending and free vibration problems of bilayer beams. Based on static mechanical equilibrium and energy equilibrium, the static and dynamic governing equations of bilayer beam are established.

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators
Advanced Robotics Research, EarlyView.Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

Inherently Disordered Auxetic Metamaterials
Advanced Science, EarlyView.Inherently disordered auxetic metamaterials based on random chiral Delaunay triangulations are designed and investigated using numerical simulations and experimental tests. These disordered frameworks exhibit orthotropic behavior and a large negative Poisson's ratio (ca.

On the general theory of chaotic dynamics of flexible curvilinear Euler–Bernoulli beams [PDF]
Nonlinear Dynamics, 2014 We present chaotic dynamics of flexible curvilinear shallow Euler–Bernoulli beams. The continuous problem is reduced to the Cauchy problem by the finite-difference method of the second-order accuracy and finite element method (FEM). The Cauchy problem is solved through the fourth- and sixth-order Runge–Kutta methods with respect to time. This preserves

Advanced Science, EarlyView.This study proposes a piezoelectric interface modification strategy to amplify the piezoionic effect. The piezoelectric interface generates an intrinsic electric field, which not only drives rapid ion migration but also concentrates polarized ions on the interface. The flexible sensor delivers superior performance, such as a quick response rate, strong

, 2001 In this paper we study systems in which the system operator, $A$, has a Riesz basis of (generalized) eigenvectors. We show that this class is subset of the class of spectral operators as studied by Dunford and Schwartz.

Advanced Intelligent Systems, EarlyView.This paper introduces an origami‐inspired, lightweight, reconfigurable instrument for robot‐assisted minimally invasive surgery. Its foldable design enables tiny access, tunable compliance, and multifunctionality, serving as a tool introducer or deformable grasper that safely manipulates delicate bowel tissue.
