Abstract

The crack initiation of tow eye is doing research on crack propagation. Finite element method simulation used in the tow eye crack growth analysis. This simulation used ANSYS software to study about characteristic during loading time based on load history. The static approach is chosen in this research to purposes failure mode on the tow eye sample. Testing for the material of tow eye to determine the simulation, such as tensile test, and Optical Emission Spectroscopy test to determine the chemical composition of tow eye. On the end of test, noted that tow eye material is manganese steel, the input data from material properties is using with finite element method (FEM) based on fracture mechanic theory. The simulation with ANSYS also using Strain Energy Release (j-Integral) approach to calculate mode shape of failure. The result of simulation gives representation about the contour of crack. Finally, the conclusion of research, FEM method can be the prediction of Stress Intensity Factor and j-Integral in all of contour of crack to determine width of crack.

利用能量应变释放法分析两眼衰竭

双眼裂纹起裂是对裂纹扩展的研究。有限元模拟方法用于双眼裂纹扩展分析。本仿真采用ANSYS软件，基于载荷历史，研究了载荷过程中的特性。本研究选择静态方法来研究双眼样本的失效模式。对拖眼的材料进行模拟测试，如拉伸测试、发射光谱测试等，以确定拖眼的化学成分。试验结束时，注意到两眼材料为锰钢，材料性能输入数据采用基于断裂力学理论的有限元法进行分析。ANSYS仿真还采用应变能释放法(j积分法)计算破坏模态振型。仿真结果给出了裂纹轮廓的表示。最后，通过研究得出结论，有限元法可以预测裂纹所有轮廓的应力强度因子和j积分，从而确定裂纹宽度。
