A theoretical analysis of the problem by an engineering model based on energy balance is validated by experimental impact tests. A gas gun was used for the tests, firing high-velocity projectiles against the panels. With the analytical model, the energy absorbed by the glass/polyester panels on impact (at velocities of 140 - 525 m/s) is calculated, and therefore the residual velocity of the projectile and the ballistic limit. Both these variables are very close to the results of the experimantal tests.application/pdfengAnalytical modelBallistic ImpactGlass/polyesterCompositesconference paperIngeniería MecánicaIngeniería Industrialopen access
