Abaqus tutorials Abaqus tutorials
In this tutorial, the Simulation low velocity impact on the composite panel(three glass layers+two epoxy layers) in Abaqus has been investigated. The three glass layers are modeled as three-dimensional solid parts. The two glue or epoxy layers are modeled as three-dimensional solid part. The rigid projectile and supporter are modeled as shell parts. You can see a figure of the assembled parts below
To model epoxy behavior as a cohesive material, the traction elasticity type with damage criterion as traction separation law is used. To model glass behavior under impact load, Abaqus has several material models which they are appropriate for this type of simulation. Some of those material models are available through a subroutine code or input file capability. The dynamic explicit step with mass scale technique to reduce the time of the simulation and make stability in model are implied. The ideal or perfect contact is assumed among the glass and glue interfaces. The general contact algorithm is selected to consider all contacts in the contact domain. The fix boundary conditions is assigned to the bottom rigid plate and initial velocity to the projectile. The mesh should be fine to obtain correct results
After the first simulation, all results such stress, strain damage, failure, and …are available. In the second simulation the results from the first analysis is used as an initial situation for the the second model. In the second model, the model is damaged at first and after that, you can see also all output like the below figures
