Sayahlatifi, Saman, Shao, Chenwei, McDonald, André, Hogan, James D.
This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum–alumina (Al-Al2O3) metal matrix composite (MMC) coatings subject to indentation and quasi-static compression loading. Based on microstructural features (i.e., particle weight...

Jarauta, A., Zingan, V., Minev, P., Secanell, M.
A multi-dimensional, compressible fluid flow solver, valid in both channel and porous media, is derived by volume-averaging the Navier-Stokes equations. By selecting an appropriate average density/velocity pair, a continuous, stable solution is obtained for both pressure and velocity. The...

Parameters of the honeycomb core, such as cell size and foil thickness, as well a s the material of the core, influence the ballistic performance of honeycomb-core sandwich panels (HCSP) in the case of hypervelocity impact (HVI) by orbital debris. A dedicated ballistic limit equation (BLE) that...

This study focuses on simultaneous vibration suppression and energy harvesting in a broad frequency band. For this purpose, a variant nonlinear energy sink (NES) is developed. The developed variant NES consists of a nonlinear oscillator and an electromagnetic energy harvester. Unlike a true NES,...
