Observing the simulation behaviour of Magnesium alloy metal sandwich panel under cyclic loadings

This study aims to investigate the delamination effect of a metal sandwich panel using four-point bending simulation under continual spectrum loading. The most recent core designs have cavity that can increase vulnerability in terms bonding strength constant cyclic is simulated loading different design configurations, which are rounded dimple, hemispherical and smooth surface design. There two types conditions used; no pre-stress loads with variable stress ratios based on Gerber life theory. Results showed dimple enhanced mechanical behaviour fatigue performance about 33% 5%, respectively, compared It highlighted modification could be beneficial enhance panels prevent early extreme such as for against high impact load continuous load.
