Abstract: Using the simplified Reissner's equation of axisymmetric shells of revolution, the nonlinear bending of a corrugated diaphragm with a plane central region under compound load has been investigated. The characteristic curves of the diaphragm can be obtained by means of the method of integral equation. Numerical results of an example are given in the end of the paper. 
Keywords: corrugated diaphragm, plane central region, non linear bending, elastic characteristic, circular plate.
