Flight Loads Analysis with Inertially Coupled Equations of Motion

, 2005
In this work an approach for simulation of a large passenger aircraft with high precision equations of motion and a new method of dynamic loads calculation is presented, which can be used for maneuver and gust loads analysis in the time domain. Equations

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Parallel Implementation and Application of the Random Finite Element Method

, 2011
Geotechnical analyses have traditionally followed a deterministic approach in which materials are modelled using representative property values. An alternative approach is to take into account the spatial variation, or heterogeneity, existing in all geomaterials. In this approach the material property is represented by a mean and standard deviation and

Application of a Discontinuous Galerkin Method to Predict Airframe Noise

, 2009
Unstructured grids greatly ease the mesh generation process in the case of complex geometries. The Discontinuous Galerkin Method (DGM) provides a robust, high-order accurate discretization even on this type of grid.

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale
