Penta graphene has attracted much attention due to its unique carbon atom topology and
novel properties in these years. In this paper, we study the crack growth and material
fracture mechanism of penta graphene under uniaxial tension systematically via molecular
dynamics simulation. We explore the mechanism of stress field and influencing factors
during crack growth on penta graphene. The mechanical properties of penta graphene and
graphene are compared and analyzed. The effect of temperature on the mechanical …
