摘要

利用Cranz-Schardin相机采用焦散法进行了热钢化玻璃裂纹扩展和发散的高速摄影研究。使用经回火的10mm厚玻璃板作为试样。即使在10mm厚的钢化玻璃中，也可以观察到并澄清作为裂纹发散的两种类型的分叉和分支。可以证实分叉型和分支型之间阴影点大小的差异。

Crack propagation and divergence phenomena observed by Caustics method in tempered glass

High speed photography by Caustics method using Cranz-Schardin camera was studied for crack propagation and divergence in thermally tempered glass. Tempered 10 mm thick glass plates were used as a specimen. Two types of bifurcation and branching as the crack divergence could be observed and clarified even in 10 mm thick tempered glass. The difference of the shadow spot sizes between bifurcation type and branching type could be confirmed.

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.
