Bending analysis of conoidal shells with cut-outs

Abstract

The bending analysis of conoidal shells using curved quadratic isoparametric elements has been presented in an earlier paper by the authors. The present study on the effect of cut-outs in conoidal shells is made on the basis of the same formulation. With the examples of five types of cut-outs, the shell behaviour with reference to that of a solid truncated conoidal shell under the same intensity of loading and same boundary conditions is studied and presented in detail. The comparative performances of longitudinal and transverse cut-outs of equivalent size are also included in the study.
