Recently, nanotechnology has attracted a considerable scientific interest due the potential new uses of non-particles, which can improve the properties of cement mortars or concretes, such as Nanosilica. Nanoparticles, like those of nanosilica, have been shown to have unique physical and chemical properties different from those of conventional cement additions. Nanosilica was used either to replace part of the cements or as an addition to improve the performance of the cement such as accelerating the hydration of ...

This work is initially devoted to study the cracking behaviour of a small composite wind turbine blade. In order to choose material, the blade is manufactured by different materials (glass/epoxy, carbon/epoxy, Aluminium, and PVC). Considering loads and boundary condition, we study in static analysis the stress, strain and displacement, in dynamic analysis the modes shape and naturals frequencies, in fracture analysis the stress intensity factor, crack initiation and crack growth in order give the results by finite...
