摘要：
The aim of this work was to study the fatigue behaviour of aluminium foam during compression-compression cyclic loading under an applied load. The reason was to estimate the amount of load for a fatigue life of 105 cycles with or without a small amount of permanent plastic deformation determined to be less than 1 mm. The samples were subjected to cyclic loading under various forces (proportion of level force estimated from a uni-axial compression test) in one given direction due to the elimination of the foam anisotropy. Moreover, the fatigue behaviour of the aluminium foam under compression-compression cyclic loading is described macroscopically. It was revealed that 50 % of the applied load estimated from the un-axial compression test is sufficiently low for a fatigue life 10(5) cycles in the case of a foam density of 0.211 +/- 0.007 g cm(-3).
