Molecular dynamics simulations of cracked nanocrystals of aluminum were conducted to investigate the effects of crack length and grain boundaries. Results showed that the grain boundary had a beneficial effect on fracture resistance, increasing fracture toughness by almost four times for bi-crystals.
Molecular dynamics simulations of cracked nanocrystals of aluminum were performed in order to investigate the crack length and grain boundary effects. Atomistic models of single-crystals and bi-crystals were built considering 11 different crack lengths. Novel approaches based on fracture mechanics concepts were proposed to predict the crack length effect on single-crystals and bi-crystals. The results showed that the effect of the grain boundary on the fracture resistance was beneficial increasing the fracture toughness almost four times for bi-crystals.
