本文是对“复合材料格栅加筋板屈曲荷载优化”一文的讨论。本文提出了一种改进的涂抹法来研究加筋复合材料圆柱壳的屈曲行为。虽然这是一种简单有效的方法，但在将壳体和加劲肋的刚度矩阵进行叠加和计算等效刚度参数时，存在着基本的误差。这个错误通过两个简单的例子来说明。
This paper is a discussion of “Optimization for buckling loads of grid stiffened composite panels”. That paper presented an improved smear method to study the buckling behavior of stiffened composite cylindrical shells. Although this is a simple and efficient procedure but there is a basic error in superimposing the stiffness matrices of the shell and the stiffeners and calculating the equivalent stiffness parameters. This error is shown by two simple examples.
