Abstract

In order to investigate new crack generation in thermally tempered glass, crack propagation and crack divergence were observed using Cranz-Schardin high speed camera. Tempered glass of 3.5 mm thick was used as a specimen. Generation of cracks due to two crack-collision was also observed in 3.5 mm tempered glass, as well as those observed by Caustics method in 10 mm thick tempered glass. Regarding the presence/absence of new cracks the dependence of two cracks on the collision angle was confirmed. Considering that it is based on the synthesis of stress 𝜎CR generated at the crack tip, tensile stress necessary for the new crack generation could be created.

3.5mm厚钢化玻璃中两裂纹碰撞产生的新裂纹

为了研究热钢化玻璃中新裂纹的产生，采用crz - schardin高速相机对裂纹扩展和裂纹发散进行了观察。采用3.5 mm厚的钢化玻璃作为试样。在3.5 mm钢化玻璃中也观察到两次裂纹碰撞产生裂纹，在10 mm厚钢化玻璃中也观察到两次裂纹碰撞产生裂纹。对于新裂纹的存在与否，确定了两裂纹对碰撞角的依赖关系。考虑到它是基于裂纹尖端产生的应力𝜎CR的综合，因此可以产生新裂纹产生所需的拉应力。

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.
