本章提出了细化梁理论的统一表述。这项工作嵌入到高阶梁 [1] 和板/壳 [2] 模型的 Carrera 统一公式 (CUF) 框架中。 CUF 是分层的，即公式的顺序被视为分析的自由参数。 CUF 的层次特征使我们能够以统一的方式处理细化的梁理论，而不需要特殊的公式。此外，可以通过本梁建模来分析任意横截面几何形状。
This chapter presents a unified formulation for refined beam theories. This work is embedded in the framework of the Carrera unified formulation (CUF) for higher-order beam [1] and plate/shell [2] models. The CUF is hierarchical, that is, the order of the formulation is considered as a free parameter of the analysis. The hierarchical features of CUF permit us to deal with refined beam theories in a unified manner with no need of ad hoc formulations. Moreover, arbitrary cross-section geometries can be analyzed by means of the present beam modeling.
