A plastomechanical preliminary design has been developed for sandwich sheets with a viscoelastic and shear transmitting interlayer. Especially displacement and delamination are described with preliminary design and verified with numerical calculations. But this plastomechanical preliminary design shows improvable deliverables. Especially the inaccuracies of the strain distribution over thickness and bending angle should be improved. Therefore many experimental forming tests with different materials are planned. Instead of symmetrical sandwiches, significant improvements can be achieved by e.g. reducing the thickness of the outer metal layer. With increasing the number of sheets the total thickness of the composite can be achieved. On the other hand thin inner layers tend to
