TL;DR: In this paper, an efficient and robust algorithm of non-probabilistic reliability-based design optimization (NRBDO) is proposed based on convex model, where the inner loop concerns a Min-max problem for the evaluation of reliability index, and an enhanced chaos control (ECC) method is developed on the basis of chaotic dynamics theory.

TL;DR: An integrated framework of exact modeling, isogeometric analysis and optimization for variable-stiffness panels is developed for the global optimum, and the proposed method is able to provide a more efficient optimum design with significant less computational cost compared to other traditional methods.

TL;DR: In this article, the authors reported new numerical results of thermal-mechanical buckling of functionally graded rectangular and skew plates (FGPs) under combined thermal and mechanical loads, and the numerical responses of buckling are computed using IGA based on the first-order shear deformation plate theory (FSDT) without shear-locking effect.

TL;DR: In this paper, the buckling behavior of composite variable-stiffness panels is investigated based on IGA, whose main feature is that the continuity of fiber angle on the whole panel is guaranteed.

TL;DR: In this paper, the flow field function containing a uniform field and several vortex fields is used to represent the fiber path, and a bi-level optimization framework of variable-stiffness panels considering manufacturing constraints is then proposed.
