Abstract: It is observed in practice that the classic (conventional) method as well as the finite element method, when using beam elements, to evaluate the strength and stiffness of a pressframe, gives results differing substantially from actual values. This discrepancy between experimental and theoretical results can be considerably narrowed if the stress-deformed state of the corner zone is separately considered in the computation of the overall strength and stiffness of the pressframe. By means of the application of the theory of thin-wall curved beam with large curvature it is economically possible to analyze the stress-deformed behavior of the pressform in general and the corner zone element in particular with fair reliability. In the present paper this method is applied to a mechanical C-frame press.
