The scientists investigated how laminated glass made from different types of glass and layers behaved when hit by a metal object. They tested glass with two types of plastic layers and different glass strengths to see how they reacted to impact. Suspended by steel ropes to avoid external influences, the glass was studied using a mix of experiments and computer simulations. They found that the type of glass and plastic layer used affected how the glass broke and absorbed impact. Their work helps in understanding how laminated glass structures respond to impact and can be used to design them better for safety.
