Abstract

The feasibility of overcoming “cutoff” effects in four versions of the theory employing classical and mixed functionals is analyzed for sample problems involving the stress concentration near a hole in composite spherical shells with different thicknesses and transverse shear rigidities. Recommendations on the choice of theory are given depending on the shell parameters. A class of “not very thick” shells with a low shear rigidity is found for which all the versions of the theory yield an acceptable computational accuracy.
