To get clear the vibration mechanism of sandwith shell using experiment method, a double-layered plate is designed for sandwich by matching equivalent impedance. Numerical analysis conducted, and In 10Hz-4000Hz, differenceof impedance from should be less than 10%. A new design given plate, which quite simple construction. Then, could applied to conduct series tests influence core material on st...

This study evaluated the effects of sintering temperature on Vickers microhardness and three-point flexural strength values two multi-layered zirconia materials. Multi-layered systems with four distinct layers were selected: DD cube ONE ML (4Y-TZP) cubeX2 (5Y-TZP). In total, 96 plate-shaped A2-shade specimens obtained using individual these The then divided equally into batches three different ...

This paper proposed analytical solutions for the buckling analysis of rectangular single-layered graphene sheets under in-plane loading on all edges simply is supported. The characteristic equations of the graphene sheets are derived and the analysis formula is based on the nonlocal Mindlin plate. This theory is considering both the small length scale effects and transverse shear deformation ef...
