Abstract

In a bicycle-vehicle or a motorcycle-vehicle accident, the head of an adult rider with a helmet is very likely to impact the windshield laminated glass. Such a complex impact phenomenon normally involves head injury, windshield failure, and helmet damage. The main purpose of this work is to present...
