Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

A novel director-based Bernoulli–Euler beam finite element in absolute nodal coordinate formulation free of geometric singularities [PDF]
Mechanical Sciences, 2013 A three-dimensional nonlinear finite element for thin beams is proposed within the absolute nodal coordinate formulation (ANCF). The deformation of the element is described by means of displacement vector, axial slope and axial rotation parameter per ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This paper proposes a hybrid control strategy for flexible‐link manipulators that combines offline trajectory planning with adaptive tracking to suppress residual elastic vibration (REV) under unknown bounded disturbances. A rigid–flexible coupling dynamics model is first established using the floating‐frame method and Lagrange's equations ...

Dynamic boundary control of a Euler-Bernoulli beam [PDF]
IEEE Transactions on Automatic Control, 1992 A flexible beam, clamped to a rigid base at one end and free at the other end is considered. To stabilize the beam vibrations, a dynamic boundary force control and a dynamic boundary torque control applied at the free end of the beam are proposed. It is proved that with the proposed controls, the beam vibrations decay exponentially.

On Dynamic Properties of Two Models of Beam on Nonlinear Foundation Subjected to Moving Load
Engineering Transactions, 1993 The subjects of consideration are the infinite Bernoulli - Euler and Timoshenko models of a beam resting on a nonlinear visco-elastic foundation. The beams are subjected to a distributed inertialess loading constant in a given sector and moving with a ...

Structural Concrete, EarlyView.Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Control of networks of Euler-Bernoulli beams [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 1999 In this very important paper the problem of exact controllability of hyperbolic systems of networks of Euler-Bernoulli beams by boundary action is considered. The authors show (Petrovsky systems on one-dimensional networks are considered) how to manage the network structure and the controllability problem using the Hilbert Uniqueness Method (HUM) of ...

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT In this contribution, we present a FE2${\rm FE}^2$ model for shear‐flexible beams with a lattice‐like meso structure. The meso structure consists of a network of beams. The meso ‐ and macroscale are coupled by means of the Hill–Mandel condition.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review
Journal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.
