Summary: | Multilayered materials have been gathering much interest in the last decades because of their possible extraordinary combination of strength and ductility. The significance of the mechanical properties of metallic multilayers becomes from both the importance of their possible applications and the need to understand the influence of the length scale on a variety of the deformation processes, for example deep drawing or stamping. These attractive materials can be applied in many fields as an effective replacement for the conventional structural materials. In the present study it was expected that the way of manufacturing and the morphology of multilayered structure directly affect the deformation mechanisms. The investigated materials were joined into multilayered system by the explosive welding process. This method allows joining completely different from point of view of physical and mechanical properties materials. The three-layered material built with two pure copper sheets as an outer layers and ferritic steel between them was investigated in the deformation tests i.e. tensile, bending and the Erichsen cupping tests. The Digital Image Correlation system was used to evaluate deformation behavior of each layer and the whole multilayered system. The experimental investigations were supported by the numerical simulations using the commercial QForm Software. |
