文摘
- •
The bending and the free vibration behaviors of strain gradient-based nanocomposite plates with surface elasticity are investigated.
- •
The plate is modeled according to the modified strain gradient theory and Gurtin and Murdoch surface theory.
- •
The plate is made of a composite material with a nanocrystalline matrix and nanoparticles reinforcement.
- •
A multi-phase size-dependent micromechanical model for materials with nano-inhomogeneities is developed.
- •
Effects of the plate's size and material structure on the deflection and natural frequencies of the plate are investigated.
