N2 - In this research, a multiscale modeling framework is developed and applied to the analysis of adhesively bonded composite joints under mechanical loading. The primary goal is to obtain an improved understanding of damage initiation and failure at the relevant length scales and predicting the consequent effects at the structural scale. The methodology utilizes damage information at the atomic level, addressed using molecular dynamics (MD), and couples it with a method of cells based micromechanics model for the nonlinear and damage analysis of carbon fiber reinforced polymer (CFRP) composite. This damage analysis technique is then used to predict the multiscale nonlinear effects in hot-spot zones, such as the adhesive/adherend interface, in adhesively bonded T-joints which will assist in the development of methods for prevention or delay of the most common forms of failure in such built-up components.
