摘　　要：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。The damage process, fracure observation and numerical simulation studyof a tensile aluminium plate under the intense CO2 laser radiation is presented. If is found thar cracking initiates at the intersection of the laser radiation edge and a diameter which is perpendicular to the tension direction, and then, develops outward along this diameter until faiture.
