  • propagation : 持續培養
  1. Wherefore, other two energy - based fracture parameters are put forward : the stable fracture energy gfs, indicating the average energy dissipation during the crack stable propagation and the unstable fracture energy gfu, corresponding to the crack unstable fracture stage. wedge. ? splitting specimens are tested with a view to understanding those two parameters " size effect in terms of the initial crack length a0

    本文提出兩個能量型斷裂參數即穩定斷裂能g _ ( fs )和失穩斷裂能g _ ( fu )分別表示裂縫穩定擴展和失穩擴展階段的能量損耗,並採用楔入劈拉試件( ws )對這兩個參數相對初始縫長_ 0的尺寸效應進行了分析。
