Abstract (EN): The main purpose of this work is to study the bending behavior and deformation mechanisms of sandwich panels with AlSi7-alloy foam cores obtained by the powder metallurgy method. For this purpose, quasi-static three-point bending tests were performed on samples of AlSi7-alloy foam sandwich panels at different cross-head displacement rates: 1, 10, 20, 40 and 80 [mm/min]. Load-deflection values were registered during the bending test and further transformed into bending moment-rotation data. Obtained results show that different failure collapse modes can be obtained for samples with identical nominal dimensions, depending on the cross-head displacement rate.
