First layer of glass, silver plating (?) Possibley, Silver deposited on inner side of first layer of glass, later joined to inner glass.
The starting point of the fracture is the longitudinal (parallel to lower edge, lengthwise, sideways , along lower edge of windshield?)
Two fracture points (1.6 mm apart) were observed on the interlayer side of the outer plate. (fracture started at same time from 2 points along lower edge of windscreen?)
Place to look (Nihongo) fracture mechanics...http://www-it.jwes.or.jp/ae/free/ae-1204/ae-1204-00.pdf also http://www.madehow.com/Volume-1/Automobile-Windshield.html The coated plastic substrate simply replaces the laminated plastic film in conventional windshields. The film can be made in any color and can transmit up to 90 percent of the visible light. Another coating is a glaze that consists of*** silver*** coating used in combination with other metal oxide layers. This glaze can reject up to 60 percent of the total solar energy, reducing the infrared energy by 56 percent.
