摘要

The user-defined element combined spring (C/SPRING) which is implemented in theTILLY program can be used to model different types of elements. Based on the concept of the Discrete Element Method (DEM), element definitions are given for: (1) beam element with shear deformation; (2) four noded plane stress element; and (3) four noded plate bending element. An easy link can be made to the normally applied Finite Element Method (FEM) approach. This is done to give more insight and to clarify some choices. The theory presented is used in two examples. Although the elements are of relative low order they are quite useful for a PC-program. The results show a good agreement with expected exact results. With the presented element derivation it should be possible to derive other type of elements in a similar way.
