摘要

PPROBLEM TO BE SOLVED: To provide a model geometry analysis method for accurately finding a curvature of a surface element even if the number of elements for a shell model is low. PSOLUTION: In analysis of the geometry of a curved surface model using a finite element method, the geometry of the model is expressed by defining the curvature by a symmetric matrix Q satisfying an equation (X-XSB0/SB)äP-Q(X-XSB0/SB)/2}=0, when a positional coordinate vector of an objective node is represented by XSB0/SB, a coordinate vector of a proximity node of this node is represented by X, and a unit vector in the direction vertical to the curved surface is represented by P.

要解决的问题：提供一种模型几何分析方法，即使壳体模型的元素数量很少，也可以准确地找到表面元素的曲率。

解决方案：在使用有限元方法分析曲面模型的几何形状时，通过用满足方程式（XX 0 的对称矩阵Q定义曲率来表示模型的几何形状。）äP-Q（XX 0 ）/ 2} = 0，当目标节点的位置坐标向量由X 0 表示时，邻近节点的坐标向量
