The objective of the study is to determine the influence of forming on the adherence properties of sheet steel laminates. Drawing is then decomposed in different deformation modes: stretching (or biaxial tension), plane strain tension, uniaxial tension and shear deformation. Two adherence tests are used -the torsion shear test (napkin-ring) and the wedge test - in order to evaluate the metal/polymer adhesion before and after deformation.
