In this tutorial Finite element simulation of air blast explosion over the glass in Abaqus-Damage analysis- has been investigated.The glass and frame are modeled as a three dimensional part.You can see a figure of the assembled parts at below
Elastic plastic material with Johnson-Cook damage criterion is used to model steel frame behavior. To model glass material ,Abaqus gives some model one of them is elastic as shear modulus,drucker prager plasticity,ductile damage criterion and equation of stat,by using those parameter the Abaqus can take results for glass. Another procedure is VUMAT subroutine or call embedded subroutine in the input file which can provide the exact results .
Dynamic explicit procedure and perfect contact between glass and frame are used. The CONWEP air blast technique to apply blast pressure on the glass surface is selected. Fix boundary condition is assigned for the frame. The mesh has a crucial role to achieve correct result ,so it needs to use fine mesh for the glass.
After the simulation all results such as damage variable for glass,stress,strain,pressure and ….can be achievable . You can see some figures of the results at below
