摘要:
差厚板由于截面非均一性导致其断裂行为与等厚板有差异,为了研究差厚板的断裂行为,采用单向拉伸实验和反复加载实验相结合的方法建立了差厚板的损伤变量与应变之间的本构关系,并将所建立的本构关系嵌入到Abaqus软件中进行了拉伸模拟实验。研究结果表明:差厚板损伤变量与应变之间为非线性关系,且损伤变量随应变增加呈现出先增加较快后较慢的趋势;采用有限元模拟得到的断裂位置、力和行程曲线与实验结果相吻合,验证了所建立损伤准则的准确性。
Abstract:
The fracture behavior of tailor rolled blank is different from that of the blank with same thickness because of its non-uniformity in cross section. To study the fracture behavior of tailor rolled blank,we built a constitutive equation between damage variable and strain by a combination of uniaxial tensile tests and repeated loading experiments. The established constitutive relationship was embedded in the Abaqus software for tensile simulation experiments. The results suggest a nonlinear relationship between damage variable and strain. The damage variable increases faster with increasing strain during early stage but slower during later stage. The fracture position and stress-displacement curve obtained by finite element simulation is well consistent with experimental results,which verifies the accuracy of the damage criterion.
