摘要

我们提出了一个由多个裁剪补丁组成的复杂CAD模型的等几何Kirchhoff-Love壳分析公式。该方法基于Herrema AJ, Johnson EL, Proserpio D, Wu MCH, Kiendl J, Hsu MC(非匹配等几何Kirchhoff-Love壳块的惩罚耦合)中提出的惩罚耦合方法，并应用于复合风力机叶片。应用力学与工程中的计算机方法2019;346:810-840 .)，并扩展到在物理或参数空间中定义的任意耦合曲线上的应用。我们提出了准备实施的详细方案。不同的数值试验验证了该方法的准确性和适用性。

Penalty coupling of trimmed isogeometric Kirchhoff–Love shell patches

We present a formulation for isogeometric Kirchhoff–Love shell analysis on complex CAD models consisting of multiple trimmed patches. The method is based on the penalty coupling method presented in Herrema AJ, Johnson EL, Proserpio D, Wu MCH, Kiendl J, Hsu MC (Penalty coupling of non-matching isogeometric Kirchhoff–Love shell patches with application to composite wind turbine blades. Computer Methods in Applied Mechanics and Engineering 2019;346:810–840.) and extended to the application on arbitrary coupling curves defined either in the physical or parametric space. We present the detailed formulation ready for implementation. Different numerical tests demonstrate the accuracy and applicability of the method.

期刊介绍： The objective of the Journal of Mechanics is to provide an international forum to foster exchange of ideas among mechanics communities in different parts of world. The Journal of Mechanics publishes original research in all fields of theoretical and applied mechanics. The Journal especially welcomes papers that are related to recent technological advances. The contributions, which may be analytical, experimental or numerical, should be of significance to the progress of mechanics. Papers which are merely illustrations of established principles and procedures will generally not be accepted. Reports that are of technical interest are published as short articles. Review articles are published only by invitation.
