摘要
有限元的实质就是将工程结构离散为各种单元以节点连接的计算模型。 2 0节点三维块单元的曲面边界能较好地逼近结构的曲面边界 ,可用于分析形状不规则。
The essence of Finite Element analyse is FEA about engineering structure dispersed into all kinds of element by using node connection.The curred surface boundary of 20 Node Solid element can nearby finely structured curred surface bourdary.It can be used to analysize the structure of the irregular shape and stress complex.
