This paper presents a theoretical, numerical and experimental analysis of the allowable (maximum) deep drawing height (DDH) of rectangular cups made of steel. In particular, a new expression to calculate the allowable DDH of rectangular deep drawing, based on the equivalent diameter concept and the volume conservation principle, is proposed and compared with those theoretical expressions currently available in the literature. Finite element method simulations together with experimental data taken from a set of 20 industrial steel parts are used to evaluate the accuracy of each theoretical expression. The results have shown that the new expression has superior precision than those existing in the literature.
