摘要：
In the present study, three-dimensional finite element (FE) analysis has been performed for determination of thermoelastic properties of carbon nanotube (CNT)/epoxy composites considering both linear and nonlinear stress–strain relations of CNT. A square representative volume element has been considered for the FE analysis (FEA), and the effect of considering nonlinear stress–strain relation of CNT on the prediction of thermoelastic properties has been determined by comparing the results with the theoretical results. Results show that in order to obtain realistic values of thermoelastic properties, the nonlinear stress–strain relation of CNT needs to be used in the FEA. Not considering nonlinear stress–strain relation of CNTs in the FEA may lead to estimating erroneous values of thermoelastic properties of CNT composites which may have adverse effect in the design of structural components made of such composites subjected to thermomechanical loading.
