纤维束断裂过程的初步研究

A Preliminary Research on the Burst Process of Fiber Bundles

以施于纤维束两端的总拉力作为外界控制参数，导出了近似的未粒断纤维数目的概率分布．在此基础上，求得未粒断纤维数目随外力变化的平均值及方差，得到了发生临界现象的条件，并求出临界点．

reating the pull force at the ends of a bundle of fibers as the control paramcter,an approxi-mate probability distribution was derived. From thithe equations of the mean value and the mean square deviation of the number of the remainder fibers in the bundle were derived.The criti-cal-point equation and the condition for critical-phenomenon;s occurring were obtained.
