The effect of interlaminar graphene nano-sheets reinforced e-glass fiber/ epoxy on low velocity impact response of a composite plate
(IOP Publishing, 2018-05)
In this study, we compare the inter-laminar effect of graphene nano-sheets (GNSs) and CNTs on the single and multiple dynamic impact response of E-glass fiber reinforced epoxy composite (GFEP). In the comparisons, raw GFEP ...
Numerical assessment of the factors controlling the acoustic response of wind turbine blades
(Canadian Acoustical Association, 2019)
The blades of wind turbine are the most critical parts of the wind turbine system, which contribute to noise generated by wind turbine due to excitation from air streams across them. In this numerical study, the effect of ...
Computational and experimental investigation of vibration characteristics of variable unit-cell gyroid structures
