Abstract

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.

钢化玻璃裂纹发散现象

使用Cranz-Shardin相机进行了高速摄影，以研究热钢化玻璃中的裂纹发散和发散角。使用回火的3.5mm厚的玻璃板作为试样。结果表明，裂纹的分叉存在两种类型的分叉和分支。发散角小于根据优化设计原理计算的值，并且呈现锐角。

期刊介绍： Strength, Fracture and Complexity: An International Journal is devoted to solve the strength and fracture unifiedly in non linear and systematised manner as complexity system. An attempt is welcome to challenge to get the clue to a new paradigm or to studies by fusing nano, meso microstructural, continuum and large scaling approach. The concept, theoretical and/or experimental, respectively are/is welcome. On the other hand the presentation of the knowledge-based data for the aims is welcome, being useful for the knowledge-based accumulation. Also, deformation and fracture in geophysics and geotechnology may be another one of interesting subjects, for instance, in relation to earthquake science and engineering.
