Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing

Advanced Robotics Research, EarlyView.
Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Influence of Slenderness Ratio on Buckling Behavior of Reinforced Concrete Columns: A Finite Element Analysis

Advances in Materials Science and Engineering
Reinforced concrete columns (RCCs) are critical load-bearing elements in structural systems, where stability is often governed by buckling, particularly in slender members subjected to axial compression.

Toward Mechanical Intelligence in Robotics

Advanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.

Buckling configurations and dynamic response of buckled Euler-Bernoulli beams with non-classical supports

Latin American Journal of Solids and Structures
Exact solutions of buckling configurations and vibration response of post-buckled configurations of beams with non-classical boundary conditions (e.g., elastically supported) are presented using the Euler-Bernoulli theory.

On Critical Buckling Loads Of Euler Columns With Elastic End Restraints

Hittite Journal of Science and Engineering, 2016
I n recent years, a great number of analytical approximate solution techniques have been introduced to find a solution to the nonlinear problems that arised in applied sciences. One of these methods is the homotopy analysis method HAM .

Non-linear finite element analysis of the dynamics of a slender cable stayed tower

MATEC Web of Conferences, 2018
The aim of the present work is to investigate the static and dynamic nonlinear behaviour of a cable-stayed tower. A continuous structural model of a slender tower is discretized by the finite element method. First the buckling and post-buckling behaviour

A new sinusoidal shear deformation theory for bending, buckling, and vibration of functionally graded plates [PDF]

, 2013
A new sinusoidal shear deformation theory is developed for bending, buckling, and vibration of functionally graded plates. The theory accounts for sinusoidal distribution of transverse shear stress, and satisfies the free transverse shear stress ...
