Isogeometric nonlinear bending and instability analysis of cylindrical composite shells reinforced with graphene platelets

In the present study, by using IGA (isogeometric analysis) method, the nonlinear bending and instability behavior of cylindrical composite shells embedded with GPLs (graphene platelets) having functional gradation is investigated. In IGA, NURBS functions are employed both to construct the geometry and to approximate the field variables. Advantages of adopting IGA include: the exact geometrical description, high accuracy and efficacy,...
