Simulation air blast explosion over sandwich panel(AL-Epoxy-Glass) in Abaqus

In this video air blast explosion over a sandwich panel made of Aluminium and Epoxy Glass layers has been simulated. For modeling blast effect CONWEP procedure is appropriate . Aluminium is modeled as three dimensional part and for modeling it’s behavior under blast load ductile damage with Johnson-Cook plasticity and for modeling composite or Epoxy Glass Hashin’s damage criterion has been used. During the detonation the panel has a large deformation and some area failed.To create a better performance between composite layouts and composite with aluminium in Interaction module Damage,Damage evolution,Geometry properties, Cohesive and Linear stiffness has been implanted. You can see some figures of this simulation at bellow
