Abstract

This comment paper aims to show that the paper contains a serious error. In the commented paper, the displacements are incorrect—two of the shape functions they are based on are erroneous, and they do not properly account for the same degree. The correct forms of all shape functions are explained more deeply here.

摘要

此评论文件旨在表明该论文存在严重错误。在评论论文中，位移是不正确的——它们所基于的两个形状函数是错误的，并且它们没有正确地解释相同的程度。这里更深入地解释了所有形函数的正确形式。
