Experimental and Numerical Study of Progressive Failure of TC4 Titanium Alloy Specimens

School of Aeronautics,North Western Polytechnical University,Xi'an 710072,China

摘要

摘要: 以商业有限元分析软件ABAQUS为平台,基于GTN金属断裂模型对TC4钛合金光滑圆形试样和两种不同缺口形状试样在单向拉伸试验中的渐进破坏过程进行数值研究,同时对比分析了几何非线性的影响在数值计算中的差异.结果表明,该模型预测TC4钛合金试样单向拉伸试验的载荷-位移曲线及宏观断裂形貌与真实试验结果基本一致.

Abstract: To predict the progressive failure behavior of ductile metals, a series of experiments were conducted for smooth and notched specimens of titanium alloy TC4. And numerical simulations were performed with the GTN damage model based on ABAQUS/explicit. Meanwhile, different numerical simulations with or without geometric non-linearity were studied by contrastive analysis. Results show that the GTN damage model can accurately and effectively predict the experimental results of TC4 specimens including load-displacement curves and macroscopic fracture morphology.
