可动边结点等参过渡元形函数的确定
摘要
本文将文[1]中的覆盖方法应用到可动边结点等参过渡元
并针对四边形等参元推出了形函数通用公式
亦给出了单元结点局部坐标参数的一种简便的确定方法.而且
上述关于四边形等参元的形函数公式可被推广到空间六面体单元.
Abstract
This paper applies the covering method to the isoparametrictransitional elements of movable boundary nodes.The general shape functionormulas for quadrilateral elements and a convenient method to calculate the local node coordinate parameters are also introduced.The general formulas can be extended to space hexahedron elements.
