This work presents a new strategy for dealing with blending requirements in the composite structures design. Firstly, new analytical expressions of blending constraints, in the polar parameters space, are derived. Secondly, a dedicated numerical strategy for the recovery of blended stacking sequences is presented. The proposed approach is implemented in the framework of the multi-scale two-level optimisation strategy (MS2LOS) for composite laminates design. The theoretical aspects of this work are supported by the application of the proposed methodology to a numerical benchmark taken from the literature. The results obtained by means of the MS2LOS based on the polar formalism outperform those reported in the literature.

这项工作提出了一种在复合结构设计中处理混合需求的新策略。首先，推导了极性参数空间中混合约束的新解析表达式。其次，提出了一种专用的数值策略，用于恢复混合堆叠序列。在多层层压板设计的多尺度两级优化策略（MS2LOS）框架中实施了所提出的方法。这项工作的理论方面得到了所提出的方法应用于从文献中获得的数值基准的支持。通过基于极性形式论的MS2LOS获得的结果优于文献报道的结果。
