  • Study on Group Behavior of Short Crack for Low Cycle at High Temperature Based on Fractal Theory
    Advanced Materials Research, 2011
    Co-Authors: Zheng Wang, Lu Wang, Kui Wang, Zi Hao Zhao
    Abstract:

    The propagation of fatigue short crack is a fractal curve, the irregular path can be described by fractal dimension. The fractal dimension of the crack implicit in many of the physical factors, such as Microstructure of Material, load conditions and so on. In this paper, the short crack for low cycle at high temperature is studied. The Material 20# steel in the various stress state is experimentally studied, the initiation, propagation and coalescence influence of short crack are observed. By analyzing experiment results, characters of crack fractal dimensions evolving with the cycle process are as follows, the behavior of short fatigue cracks satisfies fractal feature, with the development of the fatigue process, the fractal dimension is increased.

  • Study on Behavior of Surface Short Cracks for Low Cycle at High Temperature and Complex Stress State Based on Fractal Theory
    Journal of Mechanical Engineering, 2011
    Co-Authors: Zhao Zihao
    Abstract:

    From the physical point of view,the solid containing cracks is actually a non-linear dissipation system,so it can be described by fractal theory.The propagation of short fatigue crack is a fractal curve,the irregular path can be described by fractal dimension.The fractal dimension of the crack implicates many physical factors,such as Microstructure of Material and loading conditions.The short crack for low cycle at high temperature is studied.The Material 20 steel in various stress state is experimentally studied,the evolution process of initiation,propagation and coalescence of short cracks on the specimen surface are observed.By analyzing experiment results,characters of crack fractal dimensions evolving with the cycle process are as follows,the behavior of short fatigue cracks satisfies fractal feature,with the development of the fatigue process,the fractal dimension is increased.
