1. Introduction
Steel is a core material in almost every manufacturing field due to its excellent mechanical properties. In the automotive field, steel is very widely used and much related research has been carried out. On the other hand, steel has a low damping ratio, resulting in poor noise and vibration shielding. One of the solutions to this problem is to combine steel with a polymer with a high damping property. The development of steel-polymer sandwich structures with enhanced damping properties has been the subject of much research [1,2]. The interface between the steel and the polymer has to be guaranteed for the composite to have the desired effect [3]. Generally, adhesion between the metal and the polymer is not strong, so in industrial applications, the reliability of the materials remains problematic. Accordingly, much research has focused on enhancing the interfacial properties [4,5], but the reliability of the composites, which we would like to use as structural materials, is still not guaranteed. As the interfacial properties are important, several studies have been conducted on the characterization of delamination failures in steel-polymer sandwich composites. One method used in these studies is the virtual crack closure technique (VCCT) [6–10]. The VCCT is based on linear elastic fracture mechanics (LEFM) and the assumption that the energy release rate when an interface separates is the same as the energy required to close the crack. However, the drawback of this method is that it can only be used when there is an initial inter laminar crack in the interface. Also, it is dif- ficult to simulate the mixed mode and progressive delamination [11–13]. Another method is cohesive zone modeling, which is based on damage mechanics. This model was first suggested by Dugdale [14], who introduced the concept, while Barenblatt [15] introduced cohesive forces on a molecular scale. Subsequently, many researchers have worked on this model for solving the delamination problem [13,16–24]. The advantage of this method is that it allows prediction of the delamination of complex structures [25,26]. Moreover, this method is simple [12] and can be easily implemented using finite element methods [17,27–29]. Therefore, cohesive zone modeling is widely used for analyzing the delamination failure in composites. Precise methods to evaluate the interfacial properties are required for exact analysis of the delamination. These properties include the adhesion strength in both the normal and tangential directions. The most widely used method is a lap shear test [30], which measures the interfacial shear strength between the adhesive and the material in the tangential direction. Tensile adhesive
