本文介绍受拉伸载荷的铝板试件被强CO_2激光照射吋,铝板断裂破坏,断口观察以及数学模拟计算等研究。认为裂纹在垂直于拉伸方向的烧斑直径与烧斑边缘的两个交点上餡生,以后沿着直径两边发展,直至完全断裂。
This article describes the tensile load of the aluminum plate was strongly CO2 laser irradiation, fracture rupture of aluminum, fracture observation and mathematical simulation studies. It is believed that the crack is filled at the two intersection points between the diameter of the burn spot perpendicular to the direction of stretch and the edge of the burn, and then develops along both sides of the diameter until it is completely broken.
