An ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) method integrating multi-ingredients determination and fingerprint analysis has been established for quality assessment and control of leaves from Ilex latifolia. The method possesses the advantages of speediness, efficiency, accuracy, and allows the multi-ingredients determination...
Abstract Multi-principal element alloys (MPEAs) have attracted rapidly growing attention from both research institutions and industry due to their unique microstructures outstanding physical chemical properties. However, the fabrication of MPEAs with desired properties using conventional manufacturing techniques (e.g., casting) is still challenging. With recent emergence additive (AM) technique...
This study presents an approach that uses the refined zigzag element, {2,2} RZE in conjunction with progressive failure criteria to predict the ultimate strength of composite laminates based on only ply-level strength properties. The methodology involves four major steps: (1) Determination of accurate stress and strain fields under complex loading conditions using {2,2} RZE -based finite elemen...
