Intelligent Condition Monitoring of Aerospace Composites: Part I - Nano Reinforced Surfaces & Interfaces
Source abstract
Abstract
This study is part of a major research program concerning intelligent condition monitoring of aerospace composites. Specifically, it evaluates the influence of nanofillers on the reinforcement of adhesively bonded layer under mode-I fracture toughness using multiscale modelling. In this novel approach, we couple coarse–grain molecular dynamics with continuum mechanics. The molecular dynamics domain and the finite element domain are overlapped in a handshaking subdomain, The implementation of coarse–grain molecular dynamics radically reduces the size of the problem. An explicit algorithm coupling the two methodologies was developed and used to determine the energy release rates of cohesive cracks in adhesively bonded composite joints with varying amount of nano-reinforcement in the adhesive layer. Both the quality of the prediction of the multiscale model and the influence of the nanofillers are evaluated and discussed.
