Finite Element Analysis of a Steel Canister Perforating a Steel Plate.
Abstract
Finite element analysis of the transient response of thin-walled structures subjected to impact loadings becomes more complicated when a lack of axisymmetry requires a three-dimensional treatment. In such cases careful modeling is needed to provide sufficient solution accuracy while at the same time keeping computer costs down. In this report the analysis of one such structure, a cylindrical steel canister with a large circular hole in its side, is described. The problem of the canister perforating a steel plate from either normal or oblique angles is considered. SAP IV, a general purpose linear elastic structural analysis code was used. Both static and dynamic analyses were conducted. This problem was solved as a demonstration of analysis capabilities in this area. The stress and deformation results obtained are interpreted in terms of one-dimensional theory. An assessment is made of the weakening effects of the hole and of the effectiveness of a reinforcing ring and cover plate in reducing these effects. In the course of this analysis, some shortcomings were found in the model used. These are described and suggestions for improvements and further work are given. (Author)
