Element Stiffness Matrix Generator

摘要: This paper presents the basic concepts required to construct a computer code capable of deriving element stiffness matrices. The program requires only displacement functions, transformation matrices, and few control cards as input. assembles complete matrix for any type configuration functions order. is stored in an alpha-numeric array. final form printed terms numerical coefficients material geometric properties symbol form. output received or punched on ready incorporation into existing finite codes. Examples are presented two-dimensional triangular plate which displacements represented area coordinates. However, concept not limited local coordinate representations problems.
