摘要
等值线图的自动生成是塑性有限元分析系统前后置处理部分的重要组成之一,本文根据线性插值原理,提出了一种适用于三角形和四边形四节点单元类型,或者两者混合而成的通用有限元网格系统的等值线图自动生成算法。该算法简洁、实用,易于推广应用到其他领域的等值线图生成过程。
The automatic generation of contour drawingis one of preprocess-ing and postprecessing research of plastic finite element analysis system.According to the linear interpolation principle, this paper proposes thealgorithm of automatic contour drawing generation suitable for the mesh systemconsisting of 3-node trianglar elements, 4-node quadrilateral elements, and forthe mixed mesh system. This algorithm is concise, practical, andeasy to applyextensively in other fields.
