Karbon nanotüp içeren kompozit kardan milinin burulma burkulmasına ilişkin sayısal ve teorik bir araştırma

“…where 𝛼𝛼 and 𝛽𝛽 parameters are associated with the agglomeration degree of CNTs in the matrix. 𝛼𝛼 and 𝛽𝛽 parameters are considered as 9 and 0.9, respectively [30].…”

“…Table 1. Mechanical properties of nanocomposite components LY5052 Epoxy resin [30] AS4 Carbon fiber [41] MWCNTs [30] 𝐸𝐸 𝑚𝑚 (GPa) The elastic constants of MWCNTs-reinforced LY5052 epoxy resin for the MWCNTs volume fractions of 0.0, 0.25, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0 and 10%.was determined by Equations ( 1)- (11). Then, elastic constants of MWCNTs-incorporated AS4 carbon fiber/LY5052 epoxy resin were obtained by using Equations (13-(17).…”

Hierarchical meta-modelling for fast prediction of the elastic properties of stone injected with CNT/cement mortar

“…Both the matrix phase and the CNTs have been modelled assuming isotropic constitutive properties, as a reasonable simplification commonly adopted in the literature (refer e.g. to [49,50]). Given the computational difficulties involved in the modelling of large volume fractions of randomly oriented CNTs (aspect ratio≈1000) using solid elements, the modified RSA algorithm proposed in [51,52] has been adopted in this work.…”

Buckling Prediction of MWCNT-reinforced Laminated Composite Structures under Hygro-Thermo-Mechanical Conditions

“…Despite their potential, multi-scale methods have not yet widely used in the study of MWCNTreinforced composites. Only a few recent studies have tried to use multi-scale methods to explore the behaviour of these advanced composites [17,18,19]. However, these studies have primarily focused on general mechanical behaviour, leaving the specific domain of buckling behaviour -a critical aspect of structural stability -relatively unexplored.…”
