ISOPARAMETRIC STRIPED TANSFER FUNCTION METHOD FOR PLANAR PROBLEMS

In this paper, an isoparametric Strip Transfer Function Method (STFM) is developed for analysis of irregular plane problems. In the analysis, an irregular plane is divided into strip elements, which are mapped into square regions through isoparametric transforms. Discrete displacement model is built on the square. The dynamic equilibrium equations are derived by a variational principle. The equations are solved by the STFM, and the static and dynamic responses of the plane are obtained. Comparison is made between the results of the present model and those of the FEM.
