文摘
- •
Free vibrations of a micro/nano-sphere is analyzed based on modified couple stress theory.
- •
Accuracy and validity of the results are approved by comparing them with the experimental results.
- •
New scale parameters are proposed for spherical nano-gold, nano-silver and fullerene.
- •
Effects of different geometries and scale parameter on frequencies are investigated.
- •
It is approved that increasing scale parameters has more effect on higher mode numbers.
