Study of degeneration models of isoparametric element in finite element method;

The paper taked 20 nodes isoparametric element as an example and put forward a kind of numerical method combined with the Newton iterative algorithm and Gauss integral algorithm to calculate equivalent loads of prestress in body element.

Using 8-nodes isoparametric element based on Mindlin plate theory and Newmark method,the dynamic responses of both thin and thick elastic plates resting on Winkler foundation subjected to moving load are analyzed.

In this dissertation,the principle of FEM in EM was discussed,then a three-layered pavement were analyzed with 4-noded isoparametric elements.

In this paper, isoparametric elements of twenty nodes are used to calculate the body of Pulse Radar, and a 3-D FEM program was compiled.

the calculating concept was guoted,which of the internal force of the bent structuer in space,when analysing the internal force onsuch as the unit of the complex bent structuer,the relation between the equivalent element length and the assigning modulus,in order to get the certain reckoning and electricity calculating means,and verify by the fact that the example is in progress.
