What is the difference between natural cracking and human-induced cracking of car glass?
1 Answers
The differences between natural cracking and human-induced cracking of car glass are as follows: 1. Fragment size varies: Human-induced cracks tend to produce larger fragments due to external force impact, whereas natural cracks result in smaller fragments caused by internal stress without external force. 2. Impact marks differ: Examine the broken fragments for impact marks – human-induced cracks show obvious impact traces on the glass fragments, while natural cracks exhibit minimal marks. Additionally, tempered glass doesn't completely shatter into individual pieces; many fragments remain connected, making identification possible.
