Effect of shape mode and crack length on stress distribution in fiber metal laminates

Fiber metal laminates (FMLs) are widely used in various fields such as automotive and aerospace due to their high stiffness and strength to weight ratios. Moreover, they are also high fatigue resistance. In some applications such as aircraft structures, it is crucial to do a dynamic analysis in the FMLs structure. This research aims to investigate the effect of shape mode and crack length on stress distribution in fiber metal laminates. Numerical analysis is performed in this study to evaluate the stress distribution. Ten initial mode shape and crack length of 5 mm, 10 mm, and 15 mm are used as the environmental conditions of the FMLs. The results indicate that the mode shape will change the stress distribution and the maximum stress position. Besides, the crack will propagate when it received tensile stress and in opening mode.
