Abstract [eng] |
The effect of changed characteristics of the spot-welded connections on the absorbed energy, deformation form and axial shortening of typical thin-walled elements of car’s deformation zones was estimated. The experimental quasi-static and impact tests of the axial crushing of columns were performed to validate FE models which were used for the simulations to evaluate the influence of spot-welding on the mechanical behavior. The experimental results of statically and dynamically axial crushed thin-walled columns showed that the dynamically deformed thin-walled columns absorb from 10 to 50% more energy than those statically deformed. The good correlation between the results of dynamical experiments and FE simulations was obtained. The FE simulations show that reducing strength of spot-welded connections changes the behavior and decreases the amount of absorbed energy. |
