To clarify whether the nanoscale stress concentration dominated the fracture, we created titanium doglegged nanocolumns on a titanium thin film using dynamic oblique deposition. Two types of specimens were prepared: a forward specimen (loading to dogleg opening direction) and a reverse specimen (loading to dogleg closing direction). Nanoscale tensile stress concentration occurred at the dogleg corner of column in the forward specimen, whereas it occurred at the corner of column root in the reverse specimen. Fracture experiments using micro-brick specimens revealed that most nanocolumns in the forward specimen fractured at the dogleg corner. On the other hand, more than 70% of nanocolumns in the reverse specimen fractured near the column roots. These results suggest that the nanoscale stress concentration has great impact on the fracture.
