摘要
采用退化奇异等参元分网方法,利用有限元软件ANSYS,建立了含I型裂纹板的有限元模型,求解I型裂纹的应力强度因子。通过与理论公式解析解的对比分析,验证了应力强度因子数值解的合理性与准确性。对进一步深入研究I型裂纹断裂韧性有积极意义,为工程结构断裂分析提供重要参考。
Using the degenerate singular isoparametric element network method and the finite element software ANSYS,the finite element model of the plate with type I crack is established.The stress intensity factor for type I crack is solved.The rationality and accuracy of the numerical solution of stress intensity factor are verified by comparison with the analytical solution of the theoretical formula.The example in this paper is of great help for further in-depth study of the fracture toughness of type I crack,and provide important reference value for the fracture analys is of engineering structures.
