Stress concentration around several holes in structural elements

Our analysis of specific numerical results for nonclassical problems has thus established two conclusions.
1. The stresses do not increase monotonically as the holes are brought closer together (in the case of problems for shells under static loading and for plates under dynamic loading).
2. For several holes in the case of problems for plates under dynamic loading, the maxima of the stress concentration factors can occur in the interior of the main region rather than at the edges of the holes, depending on the frequency and form of the applied load.
These conclusions do not apply to classical problems (the planar problem under static loading) and must therefore be taken into account when stress concentrations are created.
Because of space limitations, the concluding part of this article was not included in the EPMESC'92 Conference Proceedings and is therefore published here in its entirety.
