An iterative algorithm for finite element analysis
收藏 引用
JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS 2004年 164卷 469-491页
作者: Laouafa, F Royis, P Ecole Natl Travaux Publ Etat CNRS URA 1652 Dept Genie Civil & Batiment F-69518 Vaulx En Velin France Inst Natl Environ Ind & RISques F-60550 Verneuil En Halatte France
In this paper, we state in a new form the algebraic problem arising from the one-field displacement finite element method (FEM). The displacement approach, in this discrete form, can be considered as the dual approach... 详细信息
