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.
