Nonlinear dynamic and crack behaviors of carbon nanotubes-reinforced composites with various geometries
Source abstract
Abstract
Abstract This study carried out finite element dynamic analyses of carbon nanotubes/fiber/polymer composites (CNTFPC) with various geometries. In the first application, the effects of CNTs on the nonlinear transient responses of doubly curved shells for various cutout sizes and curvatures are studied. The numerical results obtained are in good agreement with those reported by other investigators. For the practical application, the focus of this study is to evaluate various performances of concrete structures reinforced with a rebar-type CNTFPC. The new results reported in this article show the interactions between CNT weight ratios and crack sizes in CNTFPC-reinforced concrete structures. Key observation points are discussed and a brief design guideline is given.
