Crack Growth from Small Flaws in Larger Grains in Alumina

Crack growth in alumina was simulated for the case of small flaws in larger surface crystals to determine the range of crystal sizes and loading rates in which single‐crystal fracture energies would be expected to control fracture. This control should be expected only for large crystals and very hig...

Zusammenfassung:Crack growth in alumina was simulated for the case of small flaws in larger surface crystals to determine the range of crystal sizes and loading rates in which single‐crystal fracture energies would be expected to control fracture. This control should be expected only for large crystals and very high loading rates.
