Analysis of a Circular Cylindrical Performated Shell

The report contains a summary of the work done under a continuing research contract given to Applied Technology Associates in the field of pressure vessel design. In particular is developed the theoretical solution for the distribution of stresses in a perforated cylindrical shell. These calculations have been reduced to computer codes and are given in the appendix of the report. In addition to the computer codes developed for the effective elastic constants, the report contains a code for the analysis of a circular cylindrical shell whose surface is penetrated only over a portion. Thus the 'equivalent' elastic constants obtained can be used within the shell theory developed in the report to describe the deflections and stresses in a partially perforated shell. (Author)
