Utilizing the physical meaning of interference of notch effects in three-dimensional elasticity, the author calculated the stress concentration factors of an infinite row of spheroidal cavities subjected to tensile load. If the ratio t/p (p : pitch of spheroids, t : major semi-axis of a spheroid) is constant, the interference of notch effects decreases with the sharpness of notch t/p (p : notch radius at the end of major axis). He also calculated the stress concentration factors of an infinite body having two spherical cavities under tension by the same method. The results are in close agreement with the exact values obtained by Miyamoto.
