在极坐标系下，用有限差分法求出了正交各向异性板方程的解。边界条件是这样的，简单的支持沿着径向边缘和自由支持沿着角边缘规定。十五种不同的网格模式方程的开发，其中六个模式进行了描述。这些方程的解决方案，代表一个特定的细分板块，是由计算机程序解决。整个板的内力也通过有限差分法，利用挠度数据和计算机程序进行评估。为了评估该技术的有效性，对加肋曲钢板模型进行了试验。还进行了单独的刚度模型试验，以通过实验评估角向和径向刚度以及扭转刚度，并将其与计算刚度进行比较。板刚度的正确评估导致的分析挠度和应变，这与实验数据非常好。
The solution of the orthotropic plate equation, in polar coordinates, is obtained by the finite difference technique. The boundary conditions are imposed such that simple supports along the radial edges and free supports along the angular edges are prescribed. Fifteen various mesh pattern equations are developed; six of these patterns are described. The solution of these equations, representing a particular subdivided plate sector, is solved by a computer program. The internal forces throughout the plate are also evaluated by the finite difference method, utilizing the deflection data and a computer program. To evaluate the validity of the technique, a stiffened curved steel plate model was tested. Separate stiffness model tests were also conducted to evaluate experimentally the angular and radial stiffnesses and torsional stiffness, which were compared to the calculated stiffnesses. Proper evaluation of the plate stiffnesses resulted in analytical deflections and strains, which correlated very well with the experimental data.
