摘要
以单边穿透裂纹为背景,建立了描述腐蚀疲劳裂纹内溶液的流体运动两维方程。通过解偏微分方程组,用解析法得到了腐蚀疲劳裂纹内溶液的两维运动规律。据此,以紧凑拉伸试样为例,讨论了影响速度的各参数及裂纹内的流态。
The velocity of flow may obviously affect the chemical and electrochemical conditions within a corrosion fatigue crack. A tow-dimensional model was developed according to the continuity equation and conservation of fluid flow. The velocity of flow within the crack with a single edge-notch geometry was obtained by solving the partial differential equations with analytic method. The flow state within the corrosion fatigue crack and the influence of other parameters on the flow velocity for compact tension specimen were discussed according to the model.
