Numerical investigation of impact behaviour of sandwich fiber reinforced plastic composites/Pluostu armuotuju sluoksniuotu kompozitu smugines elgsenos tyrimas skaitiniu metodu

Finite element simulations were performed to study the behaviour under impact loading of the sandwich composite made from woven glass fiber and polyvinylester resin composite facesheets and polypropylene hexagonal honeycomb core that can be used for safety important structures. The layered structure dynamical properties associated with energy absorption and dynamical stiffness was investigated.
