In
this study, the effect of the notches on natural frequencies of ceramic
particles filled and unfilled unidirectional composite beams are investigated
numerically. Shape, number, size and location of the notch are examined for
unfilled unidirectional composite beam. Moreover, the effect of the particle
additives on the natural frequency of the composite beam with V notch is also
examined. Three types of notch shape are considered: U, V and square (S). SiC,
Al2O3 and B4C are used as the additive particles. According to the results,
minimum natural frequency is found in the S notch. Furthermore, it can be seen
from the results that natural frequency of S notch is the most affected by
increase in the number, size and location of notch. As for the effect of the
particle additives, maximum natural frequency is found in the beam with filled
B4C and V notch as compared with the others.
