Method & Evidence

AimTo develop and validate a multiscale modeling technique for predicting the mechanical behavior of carbon nanotube-reinforced structural adhesives.

MethodTheoretical and Experimental Investigation

ProcedureA multiscale modeling technique was developed by integrating atomistic constitutive laws into a continuum framework. This involved representing atomic bonds as load-bearing continuum elements and using molecular dynamics to derive constitutive behavior. A nanoscale representative volume element was created to model the carbon nanotube, adhesive, and their interface. This model was then used in analytical and finite element methods to predict the bulk composite's response. The theoretical findings were validated through experimental testing.
