Abstract

An account is given of a fairly extensive numerical work on the stress problem of large sized elliptic holes and cracks in cylindrical shells. The work is a logical extension of the available perturbation solutions which are of limited use in practical applications. The results generated here are of direct practical use because they cover a wide practical range of the parameters involved. The analysis also serves to establish the range of validity of the perturbation solutions. The differential equation approach does not seem to have been used earlier in the analysis of crack problems in shells. The paper thus provides an interesting alternative to the existing methods particularly when more complicated problems involving, for instance, elastoplastic analysis are to be solved. Of particular interest should be the 'hybrid' technique developed here for satisfying the boundary conditions in a crack problem.
