One of the most remarkable properties that structures made of Nanomaterial possess is their light in weight and high fracture strength (Zhang ZN, Theo Appl Fract Mech 49:233–241, 2008). For this analysis, material mathematical model for Nanomaterial is developed by using Virtual Internal Bond (Thiagarajan G, Jimmy Hsia K, Huang Y, Eng Fract Mech 71:401–423, 2004). i.e. VIB model with VU-MAT subroutine code to find out various results. Nanostrip model is tested by applying various boundary conditions and loading conditions, and response is investigated. When VIB model is applied to nanomaterial, beyond critical decreased thickness, uniform stress distribution is observed with increased fracture strength. The VIB model gives that, as the strip thickness reduces to below this critical thickness, the fracture strength no longer depends on the structure size and remains at the theoretical strength level. For Nanocomposites model also carried analysis for six different fiber and matrix models with VIB model, for that find out which Nanocomposites model is best suitable under the same loading and boundary conditions.
