N2 - A micromechanical modeling framework that integrates an interphase damage model is used to study damage evolution, and failure in radially-grown carbon nanotube (CNT) reinforced nanocomposites. The atomistically-informed damage model is developed using the continuum damage mechanics approach with damage evolution equations derived using molecular dynamics simulations. The developed damage model is integrated with a high-fidelity micromechanical analysis and captures the underlying physical behavior that could be attributed to the enhancement of the out-of-plane properties at the higher length scales. To illustrate the effects of nanoarchitecture, the response of the radially-grown CNT nanocomposite is compared with that of the traditional carbon fiber reinforced polymer (CFRP) composite.
