Generalized Multi-Symplectic Numerical Implementation of Dynamic Responses for Saturated Poroelastic Timoshenko Beam

Xibei Gongye Daxue Xuebao, 2020
Based on the porous media theory and Timoshenko beam theory, properties of dynamic responses in fluid-solid coupled incompressible saturated poroelastic Timoshenko beam are investigated by generalized multi-symplectic method.

Free vibration of axially loaded multi-cracked Timoshenko beams

Magazine of Civil Engineering, 2020
In this paper, the free vibration of axially-loaded, multi-cracked Timoshenko beams with differing boundary conditions, namely, hinged-hinged, fixed-fixed, fixed-hinged, and fixed-free is studied.

Optimal Cantilever Dynamic Vibration Absorbers by Timoshenko Beam Theory [PDF]

Shock and Vibration, 2004
A double‐ended cantilever beam as a distributed parameter dynamic vibration absorber has been applied to a single‐degree‐of‐freedom system subjected to harmonic forces.In this investigation, the beam has been analyzed under the well known model of Timoshenko and the computation of best parameters is based on the Chebyshev’s optimality criterion.This is

Vibration and buckling of thin-walled composite I-beams with arbitrary lay-ups under axial loads and end moments [PDF]

, 2013
A finite element model with seven degrees of freedom per node is developed to study vibration and buckling of thin-walled composite I-beams with arbitrary lay-ups under constant axial loads and equal end moments.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Size effects on free vibration of heterogeneous beams

MATEC Web of Conferences, 2018
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

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

Advanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
