论文摘要
在本文中，我们使用iSOODEMENETRIC KIRCHHOFF板来近似采用经典层压板理论的复合层压板。同时考虑了同一几何圆锥形和搭配配方。在此框架内，通过有效的后处理技术，基于以强形式直接强加平衡，依靠准确性和较高的连续性，通常由等差异分配授予的较高的连续性，从而恢复了层间应力。拟议方法的有效性通过广泛的数值测试证明。
In this paper, we use isogeometric Kirchhoff plates to approximate composite laminates adopting the classical laminate plate theory. Both isogeometric Galerkin and collocation formulations are considered. Within this framework, interlaminar stresses are recovered through an effective post-processing technique based on the direct imposition of equilibrium in strong form, relying on the accuracy and the higher continuity typically granted by isogeometric discretizations. The effectiveness of the proposed approach is proven by extensive numerical tests.
