A scaling method based on dimensional analysis was recently used in the research to predict the behaviour of the full scale model. However, this approach has a little impact on the deep drawing process due to the complexity of the structures. In this paper, zeroth-order finite similitude approach based on continuum mechanics is used to overcome these limitations. In this method, two spaces are assumed (physical and trial spaces) which are scaling by using transport equations (volume, mass, momentum and energy) with different time scaling, and dimensions. The aim of this paper is to introduce a new technique which has the ability to scale the full-scale cylindrical deep drawing process where the blank sheet of the full-scale model made from magnesium and conducts under a low-velocity and comparing with trial models where the blank sheets made of steel 3034, aluminium 7074 and copper OFHC. The numerical simulation of the deep drawing under the low-velocity is investigated by using the commercial finite-element program (ABAQUS 6.14). Results showed the capability of this new approach to accurate estimation of the full-scale model behaviour from the different trial material models, also an excellent correlation given with the force-time history.
