EIGEN VALUE PROBLEMS IN AXIALSYMMERICAL CURVED PLATES

Abstract

As it is well known, the finite element method (FEM) has witnessed a wide spread due to the advantages it presents. The method of finite elements is remarkably efficient mainly in cases of linear problems, especially if the computer program is used together with pre-processor and post processor programs. In this way the effort required in preparing the data and in processing the results is reduced to a minimum. However, the utilization of general finite element programs presupposes as a prerequisite access to powerful computers with rapid and large memories. In many cases it is advisable to use programs specialized for a certain type of problems or eigen value problems, whenever the employment of a general-type programe becomes extremely clumsy. Starting from these considerations, the authors have proposed to elaborate a program specialized in solving eigen value problems for axially symmetrical curved plates.
