A geometrical discontinuity in a body, such as a hole or a notch result in nonuniform distribution of stress at the vicinity of discontinuity. At the region near the discontinuity, the local stress will be higher than normal stress distribution.

A geometrical discontinuity in a body, such as a hole or a notch result in nonuniform distribution of stress at the vicinity of discontinuity. At the region near the discontinuity, the local stress will be higher than normal stress distribution. Correct Answer True

The stress concentration occurs at discontinuity. The relative cross-sectional area of a specimen with a discontinuity is lower than the sample without discontinuity. But the value of total stress remains the same for both the specimen, so the extra stress per unit area will accumulate at a discontinuity in the form of stress concentration.
