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