One possibility to achieve lightweight construction is the use of sandwich sheets. In this paper die behavior of the interface layer between steel and core is analyzed with single lap shear tests. The relation between adhesion promoter thickness and shear strength is carried out. Based on the experimental results a linear-elastic linear-plastic interpolation approach was suggested and transferred to a user material routine with cohesive elements in LS-Dyna. With consideration of the user material the single lap shear tests were simulated
