文摘
In the context of lessons learned from the second Sandia Fracture Challenge summit and observed shortcomings in our blind predictions, we revisit finite-element-based failure modeling of the Ti-6Al-4V sample. Anisotropy, rate effects, and thermal softening are used to model strength; damage mechanics is used to model failure; a non-local approach is used to mitigate mesh-dependence of results. We obtain upper and lower bound force versus crack-opening displacement curves and the means of the quantities of interest are found to meet the requirement of being within 10 % of the experimental results, but the predictions of more intensive quantities such as principal strain and temperature in the ligaments of the challenge sample are >10 %.
