Mimic-biology research on self-recovering mechanism of cavity-type crack

Modeling method was used to research the recovering law of inner cavity-type cracks during the processes of high-temperature plastic deformation. It was found that the self-recovering of cavity-type fault was similar to the self-healing of wound of skin and fracture. The self-recovering process of cavity-type fault was investigated according to the rule of self-healing of wound in human body. The recrystallization mechanism of self-recovering of cavity-type fault was discovered. A new method is presented to study the self-recovering mechanism of cavity-type cracks.
