Delayed Fracture of Tempered Glass Panels Due to Nickel Sulfide Inclusions

<p>Zhangjiajie's Grand Canyon Glass Bridge is a signature pedestrian and scenic bridge. The bridge is the spatial cable plane earth-anchored suspension with the main cable span of 430-meter-long and a stiffening box-girder span of 373-meter-long. The bridge deck is wholly constructed with transparent tempered glass panels . The lateral distance between two pylons at of the west side and the east side of the bridge is 45m and 50m respectively. This paper is intended to introduce some key techniques of the design along with the general introduction of the bridge.</p>

Microchemical Characterization

Nickel sulfide inclusions have been implicated in the spontaneous fracture of large windows of tempered plate glass. Two alternative explanations for the fracture-initiating behaviour of these inclusions have been proposed: (1) the volume increase which accompanies the α to β phase transformation in stoichiometric NiS, and (2) the thermal expansion mismatch between the nickel sulfide phases and the glass matrix. The microstructure and microchemistry of the small inclusions (80 to 250 μm spheres), needed to determine the cause of fracture, have not been well characterized hitherto. The aim of this communication is to report a detailed TEM and EDS study of the inclusions.

High speed photography using the Cranz-Schardin camera was performed to study the crack divergence and divergence angle in thermally tempered glass. A tempered 3.5 mm thick glass plate was used as a specimen. It was shown that two types of bifurcation and branching existed as the crack divergence. The divergence angle was smaller than the value calculated from the principle of optimal design and showed an acute angle.
