theory and experiment in predicting the strength of hybrid ‎fiber metal laminates

This article consists of three methodological stages. in the first one, a 3d numerical model of hybrid fiber metal laminates (fml) is developed inside ansys workbench explicit dynamics modulus and used to predict their strengths according to the astm d3039m-17 standard. in the second stage, hybrid fmls are produced according to the 4/3 stacking order in the laboratory environment, in line with the numerical model. pure epoxy resin is initially used then reinforced with, 0.2% clay, gnp and sio2 nanoparticles: comparative tensile tests are carried out according to the above-mentioned standards. at the final stage, experimental data, computer and theoretical (analytical) models of nanocrack formation processes in 7075-t6 al matrix nanoparticle-filled hybrid nanocomposite materials under the influence of high-speed and quasi-static deformation regimes are investigated. it is observed that there is a 5% difference between results from simulation and experiment.
