Elastic Behavior of Uniformly Loaded Circular Corrugated Plate with Sine-shaped Shallow Waves in Large Deflection

By means of modified iteration method,this paper gives approximate solution of the large deflection equations of circular corrugated plate with sine-shaped shallow waves having a central platform under uniform lateral load.A formula of initial modification coefficient β is given,and an integral is obtained for the simplification of modified iteration calculations.The results of present paper shows better agreement with experi-mental data and larger applicable range than all other existing solutions of corrugated plates.
