| 摘 要： | 本文提出了一种新的实验方法——涂层焦散线法,可用于难加工的非透明材料。作为应用,对铝试件的应力强度因子进行了测定并与有限元法的计算结果作了对比。在数据处理中采用多点法构造目标函数,并引入具有选代过程的统计试验法对其进行求解,从而提高了实验精度。

| Abstract: | A new experimental technique which can be applied to any opaque materials and called Coating-Caustics is presented in this paper. As an appltion, two cracked aluminium specimens were tested by this method. The experiments showed that this method is not only simple but also very valuable. In order to reduce the experimental error, the random search method is inducted to find the optimum of the object function. |
