| 摘要： | The continuous growth of damage from fatigue cracking is described as a two-stage process of crack initiation and crack propagation. The crack-initiation stage can be characterized by conventional laboratory fatigue tests. The crack-propagation stage is described using the Paris-Erdogan phenomenological law. Problems encountered in implementing the theory are presented and discussed. For the sake of simplicity, only Mode II (shearing mode of the crack tip) is used. Computations of the stress-intensity factors and of the number of load repetitions for propagating the crack are presented. The applicability of the above fracture approach is evaluated using a pavement design method that includes an additional term to represent the crack-propagation phase. |
