金属疲劳断裂过程中的尖点突变模型

Cusp Catastrophe Model for Metal Fatigue Fracture

    摘要
  • 摘要: 基于疲劳断裂过程中存在着突变现象的观点，对系统（由疲劳试样和疲劳试验机所组成）在疲劳断裂过程中的变化情况作了深入研究，建立了疲劳断裂过程中尖点突变的模型，并通过理论分析获得了疲劳断裂过程中突变发生的条件.

     

    Abstract: Based on the opinion that there is catastrophe phenomenon in fatigue fracture, the Whole loading system, including the test sample and the test machine, is studied.A cusp catastrophe model is presented, and the condition of the happening of the cusp catastrophe in metal fatigue fracture is obatined through theoretical analysis.
