20.500.12556/RUL-109996 Modeliranje odlepljanja trakov z različnimi modeli stika Modelling of tape peeling using different contact models S standardnimi testi odlepljanja ugotavljamo adhezivne lastnosti lepilnega traku. V zaključni nalogi predstavimo energijsko in napetostno analizo odlepljanja traku ter numerično simulacijo 90° testa odlepljanja, ki je bil razvit v Laboratoriju za nelinearno mehaniko na Fakulteti za strojništvo. V programu smo adhezijo, ki deluje med površinama, modelirali z modeli stika. Izbiramo lahko med modeli stika z eksponentno funkcijo, bilinearno, polsinusno in funkcijo v obliki trapeza. Rezultatu povprečne sile, dobljene iz eksperimenta, smo se najlažje približali pri uporabi modela stika z eksponentno funkcijo. The adhesive properties of the adhesive tape can be determined by standardized adhesive tests. In this thesis, we present the energy and stress analysis of the peeling tape and the numerical simulation of the 90° peeling test developed at the Laboratory for Nonlinear Mechanics at the Faculty of Mechanical Engineering. In the program, the adhesion that works between the surfaces can be modeled by several contact models. We can choose between contact models with exponential function, bilinear, half-sine and trapezoidal function. The result of the average force obtained from the experiment was best described when using the contact model with an exponential function. lepilni trakovi odlepljanje modeli stika sdhezija spoji adhesive tapes peeling contact models adhesive joints true false false [J.
