plate-bending moment
In Fig. 6 the strains directly on the edge of the notch (r = 15 mm) and the
strains along a concentric circle with radius r = 16 mm are given. From the
subfigures a very good correlation of the analytical and numerical results can
be observed.

Overall, it turns out that in case of all examined combinations of composite
and load, the numerically determined results and the results calculated by
use of the developed analytical methods show a high degree of agreement.
Thus, the developed fundamentals for calculations of stress concentrations at
notches in thick-walled multilayered composites represent a quick, dependable
and easily manageable alternative to a time-consuming FE analysis.
