How To Stop Cracked Windshield From Spreading [new] 【Limited Time】

Automotive windshields are composed of laminated safety glass: two layers of annealed glass bonded by a polyvinyl butyral (PVB) interlayer. A crack initiates when an impact exceeds the glass’s surface compressive strength (approx. 10,000 psi). Once formed, the crack tip concentrates stress, leading to propagation due to thermal cycling, vibration, and mechanical flexing. This paper investigates the efficacy of methods to halt this progression.
