ABSTRACT
The three stresses which may be regarded as possible maximums are the maximum tangential stress, the maximum radial stress, and the extreme radial stress at the outer rim. However, if the corrugations are designed so that the profile factor lies within the limits of the values, then the maximum tangential stress is decisive and may be computed. The tangential stress factor depends on the profile factor and varies inversely with it. The problem of calculating the stress of corrugated diaphragms has been simplified because of the use of the Standard profile for the corrugations. For this reason, the maximum tangential stress is decisive over the radial stresses. If a corrugated diaphragm, clamped at the edges, is subjected to a temperature difference between the diaphragm and the outer rim mounting structure, a radial load in the plane of the diaphragm will occur.
