Figure 6: Stress of the top graphene layers when the bubble is filled with ethanol.
From: Dependence of the shape of graphene nanobubbles on trapped substance
MD predicted radial 
and circumferential 
stress components of an optimized ethanol bubble (R∼4 nm) as a function of normalized radial distance (x) at 0 K. The results can be fitted by a polynomial function fσ(x) within the region of bubble (x<1). Inset shows the corresponding stress distribution based on the value of J2 (equation (8)).
