FINITE ELEMENT ANALYSIS OF TWO-DIMENSIONAL TIME-DEPENDENT STRESS PROBLEMS,
Abstract
This dissertation presents a feasible way of carrying out time dependent analyses of two-dimensional stress systems where the visco-elastic effect can be expressed in a Markov form. It is possible to express a wide range of creep data in this form by the use of Prony exponential series with enough terms. The procedures of the computer program are described and the results of two sample problems show that practical analyses can be obtained. The computer was utilized to compute triangular meshes automatically and plot the results, thus taking away much of the arduous labor associated with the previous use of finite element programs. The generation of influence coefficients for an elastic foundation represents a first attempt to rationalize the problems of definition of boundary conditions for such structures as dams. (Author)
