Abstract

This paper describes the development and application of a numerical model that can predict the delamination of the polymer coating from the steel substrate during deep-drawing.Experimentally characterized cohesive zones are used to describe the interface betweenthe polymer and the steel and are capable of modelling delamination or a prior partial lossof adhesion during an axisymmetric deep-drawing simulation. A parameter is proposed thatquantifies the interfacial integrity and is used to assess the influence of the tooling radii,the clearance between the punch and the die and the coating thickness on the interfacialintegrity.
