Circular hole in an infinite plate
Elastic stress, in-plane normal stress σ A σ B σ 1 σ 1 σ 2 σ 2
Elastic stress, in-plane normal stress

Values for calculation

$ σ_1 $ $ \mathrm{MPa} $
$ σ_2 $ $ \mathrm{MPa} $

Calculation

Normal stress at point $ A $

$$σ_A=3\cdot σ_1$$

Normal stress at point $ B $

$$σ_B=-σ_1$$
