Abstract

Novel lightweight developments in automobile industry are increasingly completed as hybrid constructions. Modern hybrid concepts, including metallic materials and anisotropic composites require material adapted joining concepts. In this context a special importance is given to the load-adapted design of joining areas. The overlapping area design of blind rivet connections has been presented upon an example of a constructed element car body. This load adapted connection has been designed due to elaborated and practically validated simulation model. Load adapted design such as overlapping areas has been presented due to its own development, practically proofed simulation model of hybrid CFRP/Al shear-field, which are subjected to extreme thermo-mechanical loads for different thermal expansion coefficients during the painting process. Calculation results, and so that developed FE-submodel could have been verified on the basis of carried out experimental research
on CFRP/AL-shear field and laid foundations for a design of CFRP-shear field components. This FE-submodel is applicable in realistic deformation and failure analysis of blind rivet connection with any anisotropic join partner under
thermo-mechanical loads. It is also a practical engineering-tool which reduces modeling efforts, computing methods and necessary experimental research. Additionally, described methodology can be applied in other join types (rivet, thread, press), offering the acceleration of calculation process in different material adapted connection methods in multimaterial lightweight
structures.
