Experimental and numerical investigation on low velocity impactof GLARE fiber metal laminates

In this paper, numerical and experimental investigation on low velocity impact response of aluminum reinforced epoxy (GLARE) plates is carried out with different impact energy. Continuum damage mechanics is used in the simulation of impacts onto the GLARE plates. Lemaitre’s and Barbero’s models are used for the simulation of the metal and composite materials, respectively. Damage codes for metal and composite are written in Vumat subroutine which is linked to ABAQUS FE code. Comparing numerical and experimental results, a good agreement is obtained for force and displacement histories. By increasing impact energy, the maximum contact force increases and the contact time decreases.
