Effect of friction stir processing on the fatigue performance of AZ31 magnesium alloy
(Wiley, 2023-05)
Herein, the cyclic mechanical behavior of AZ31 magnesium alloy after multipass friction stir processing (FSP) is investigated up to the very high-cycle fatigue (VHCF) regime. The grain refinement and texture evolution after ...
Effect of phase change materials on the optical path of LEDs for opto-thermal enhancement
(IEEE, 2023-05)
A novel concept based on the encapsulation of transparent phase change materials (PCMs) into the optical packaging structure of light-emitting diodes (LEDs) is presented in this article. The concept was initiated by ...
Effect of different surface treatments on retention of cement-retained, implant-supported crowns
(Quintessence Publishing Co. Inc., 2023)
To evaluate the effect of different treatments applied to titanium implant abutment surfaces on the retention of implant-supported crowns retained using resin cement. Materials and Methods: A total of 72 titanium implant ...
Gradient-based optimization of micro-scale pressurized volumetric receiver geometry and flow rate
(Elsevier, 2023-02)
This study focuses on the design optimization of a micro-scale pressurized volumetric receiver by changing geometry and flow rate constrained by the volume, outlet air temperature, and outer surface temperature. The ...

Preview control-based jumping and spot-jogging trajectory generation for quadruped robots
(IEEE, 2023)
This work presents a vertical center of mass (CoM) trajectory generation approach based on preview control for quadruped robots to accomplish agile locomotion tasks such as jumping and jogging. Conventionally, preview ...
Addressing the strength-ductility trade-off in a thermomechanical-processed high entropy alloy
(Elsevier, 2023-12-15)
High entropy alloys (HEAs) have garnered significant attention due to their exceptional mechanical behavior. However, the influence of secondary phases and dislocation substructures has yet to be thoroughly investigated. ...
An inverse synthesis method for the determination of effective mechanical properties for additively manufactured aperiodic structures with finite thickness
(IEEE, 2023)
The production of thin-walled structures via Additive Manufacturing is common for thermo-mechanical applications such as heat exchanger cores. However, accurate and efficient models predicting the effective material response ...
Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation
(Wiley, 2023-11-01)
Thermally activated atomic vibrations significantly decrease the x-ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals ...
Effect of processing parameters on the phase transformation of a high temperature copper-based shape memory alloy
(Springer, 2023-11)
In the present study, the influence of the processing parameters on the transformation temperatures and microstructural evolution in a copper-based shape memory alloy was investigated. Five times remelting in identical ...
