Abstract
The current work is devoted to the problem of the validation of dispersion curves and numerical simulations offundamental Lamb wave and shear horizontal elastic wave modes forfiber metal laminates (FML). In the pre-sent study, two types of FM laminates are considered. In thefirst case, the studied composite material consistsof 7 layers: one layer is made of aluminum alloy AW‐6060 while the rest of the layers are made of carbon/epoxy resin. In the second case, the FML is constructed of one layer of aluminum alloy and the rest six layersare made of glass/epoxy. In order to extract the dispersion curves for the fundamental S0, SH0, and A0 modes,as well as higher modes from the range 5 up to 1000 [kHz], the stiffness matrix method, is employed. In thefirst case the computations are performed for the following cross‐ply stacking sequences: [Al, ±5°6], [Al,±15°6], [Al, ±25°6],..., [Al, ±85°6]. Next, the FEM simulations of elastic wave propagation are performedin the case of plates, which are made of analyzed FML composites. In thefirst studied FML material, the fun-damental symmetric mode S0 is generated while in the second case the fundamental antisymmetric mode A0 isexcited. It occurred that in the case of aluminum alloy/carbonfibers the generation of the pure fundamentalsymmetric mode S0 is very difficult. In addition, the fundamental symmetric mode S0, the shear horizontalSH0, and the antisymmetric A0 wave modes are also present. In the case of aluminum alloy and carbon/epoxy,the pure antisymmetric mode A0 can be relatively easily generated. However, a significant dispersion phe-nomenon is visible. For the aluminum alloy and glass/epoxy, the obtained results are experimentally verified
