In this tutorial Simulation ballistic impact of steel projectile to the soda-lime glass in Abaqus-Damage investigation has been studied. Glass is a very complex material, whose modelling presents a significant challenge.Glass is very compressible and experiences densification that increases with time, temperature, pressure, and applied shear. It was demonstrated that pressure has a significant effect on its strength, where higher pressures produce higher strengths. Glass also appears to be strain-rate sensitive and its flexural strength increases with the loading rate. Its spall strength is high, and its elastic limit marks the onset of fracture upon shock loading . Glass also exhibits scale effects where smaller samples are stronger than larger ones, as could be expected from a brittle defect-containing material. It also experiences time dependent inelastic deformation and strength loss during plate impact experiment
Glass and projectile are modeled as three dimensional part which you can see a figure of the assembled parts at below
Steel material is used for the projectile as elastic Johnson-Cook plasticity with rate dependent. To model glass behavior under high rate pressure load Abaqus gives some proper material model which can be achieve from CAE,input file or VUMAT subroutine. In this tutorial input file capability is used to define material model which consider all aspect of glass behavior.
Dynamic explicit step with surface to surface contact are used. The fix boundary conditions for around the glass and initial velocity for projectile are assigned. Mesh should be fine at the impact location because the brittle failure needs small element size to have a good predict . After the simulation all damage variable for glass,stress,strain and other results can be requested. You can see some results of this simulation at below
