Abstract

Plastic analysis, while a relatively new field, has often been used for the analysis of plates and shells. This method of analysis is in some respects much easier than a comparable elastic analysis. The concepts of plastic analysis are widely accepted. Experimental tests have shown the theory to be within reasonable accuracy with the test results. In the following thesis, the author has obtained the solution for a circular cylindrical shell under blast type loading through the use of limit analysis. While similar solutions have been obtained, the analysis proposed by the author is believed to be the first solution obtained by accounting for the time effect on the inflection point. The solution obtained is compared with those results obtained by making some simplifying assumptions. It should be noted that no experimental results are available for impact loading. However, it is agreed by most experts in the field of plastic analysis, that this method is accurate within the framework of the assumptions.
