Summary
This Special Issue highlights the computational mechanics and SHM-oriented assessment of CNT/GPL-reinforced nanocomposite structures accounting for geometric and material imperfections. A central theme is the physically realistic modeling of porosity, non-uniform dispersion, and CNT/GPL agglomeration, together with their implications for stiffness degradation, imperfection sensitivity, and structural integrity. We invite contributions developing and applying advanced finite element (FEM) and isogeometric analysis (IGA) frameworks, including multiscale/homogenization approaches and defect-informed constitutive models that capture manufacturing-induced variability. Topics of interest include initial geometric imperfections; buckling and post-buckling of nanocomposite plates, beams, shells, and sandwich configurations; and defect–nonlinearity coupling. The issue also welcomes studies on the influence of pre-existing cracks/fissures, crack–defect interactions, and damage evolution on static, dynamic, and stability responses. Submissions integrating uncertainty quantification, reliability assessment, inverse identification, and structural health monitoring (SHM) concepts are particularly encouraged. Overall, the Special Issue aims to connect high-fidelity modeling with lifecycle performance and durability of next-generation nano-reinforced structural systems.
