Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Embedded column base rotational stiffness model based on beam-on-elastic-foundation theory and component method

Results in Engineering
This study establishes a spring‑based mechanical model for predicting the rotational stiffness of embedded column bases (ECBs). The model idealises the embedded column segment as a beam on a Winkler foundation and represents the base‑plate restraint ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Web rotational stiffness of continuous steel-concrete composite castellated beams

Fracture and Structural Integrity, 2019
Continuous composite beams can present a global instability known as lateral distortional buckling (LDB). The design code EN 1994-1-1:2004 provides a procedure for the verification of this ultimate limit state, in which the resistant bending moment is ...

Numerical Analysis of the Rotational Magnetic Springs for EDS Maglev Train

CES Transactions on Electrical Machines and Systems, 2022
Different from the traditional railway trains, the combined levitation and guidance EDS maglev train is more likely to rotate after being disturbed. Therefore, the rotational electromagnetic stiffnesses are significant operating parameters for the train.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Acoustic displacement triangle based on the individual element test

Latin American Journal of Solids and Structures
A three node -displacement based- acoustic element is developed. In order to avoid spurious rotational modes, a higher order stiffness is introduced. This higher order stiffness is developed from an incompatible strain field which computes element volume

Development of Air Bearing Stage Using Flexure for Yaw Motion Compensation

Actuators, 2022
This paper presents an air bearing stage that uses flexure for yaw motion compensation. The proposed stage realizes motion in three degrees of freedom (DOF), which are the X, Y, and Θz directions. To work with Θz as the rotational motion of the stage, we

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
