High velocity oxygen fuel thermal spray has been widely used to deposit hard composite materials such as WC-Co powders for wear-resistant applications. Unlike gas atomized spherical powders, WC-CO powders form a more complex geometry. The knowledge gained from the existing spherical powders on process control and optimization may not be directly applicable to WC-Co coatings. This paper is the f...

in this paper, the propagation of the waves in the laminated composite plates which is subjected to low velocity impact is investigated using the finite element method. a rigid metallic projectile with spherical nose is considered and the impact of this projectile with laminated composite is studied in this study. considering a finite element model the governing equations of the problem is disc...

The objective of this work was to characterize the cinnamon oil nanocapsule that contained alginate-chitosan as coating agents. In this work, cinamonn oil loaded chitosan nanoparticles (CS-alginate NP-cinamonn) are prepared by a two-step process including oil/water emulsion and ionic gelation. In this study, cinamon as a core material was nanoencapsulated with chitosan alginate at a ratio of 1:...

All impact analyses performed so far for the composite plates, have treated central impacts. Furthermore, investigations on influences of the in-plane biaxial compression, tension, or tension-compression preloads on various responses of the low-velocity impact, especially the indentation, have not been performed so far. In the present research, a finite element formulation is presented for resp...
