- Abstract:
-
When a brittle material fractures due to an applied stress, cracks propagate through the material causing mechanical failure. Atomically sharp crack tips at the frontier of crack propagation are predicted but have not been captured experimentally before, which requires both, atomic resolution and crack tracking at much larger length scales. Here, we combine both in-situ aberration-corrected transmission electron microscopy and large-scale molecular dynamics simulations based on a reactive for...
