对金属材料进行反复加卸载的拉伸试验后通过多参数综合判定法确定Kaiser效应点,对金属材料Kaiser效应点进行混沌特性分析,包括关联维数以及Kolmogorov熵值,发现在一定的时间范围内,Kaiser点信号具有混沌特征,并且Kaiser效应点信号的关联维数及Kolmogorov熵计算值比其前后一段时间内的计算值都低,说明Kaiser点处关联维数及Kolmogorov熵的降低意味着主损伤的发生。
Abstract
After tensile test of metallic materials by repeated loading and unloading, Kaiser point is determined by multi parameters method. Analysis on the Kaiser point signals in metal mass by chaotic kinetics, including the correlation dimension and the Kolmogorov entropy, the results show that the Kaiser point signals have chaotic characteristics, and the correlation dimension and the Kolmogorov entropy values of the Kaiser point is lower than that in the first and the back of the time, the decline of the correlation dimension and the Kolmogorov entropy values of the Kaiser point means the occurrence of the main damage.
