Paper Title:
The Consistent Description of Crack Developing Process Based upon Cottrell' Pilling up of Dislocations Model
  Abstract

The new concepts“crack nuclearation toughness”and “crack criterion number”given in this text were used for describing the different crack development steps and crack nuclearation critic condition and the fast developing critic condition of crack were suggested with them by means of Cottrellˊpiling up of dislocations model.The analysis pointed out that crack nuclearation toughness of brittle material is 1/2 of its fracture toughness and the criterion number of crack was a good parameter reflecting anti-crack toughness of material in crack developing process
