The precise finite strip method

Abstract

This paper introduces a new development for the finite strip method. The precise integration method along the space coordinate is combined with the semi-analytical analysis of prismatic domain structures and then a novel precise finite strip method is proposed. By using such a novel semi-analytical method, the structure, which is as usual discretized along the transverse direction in a prismatic domain, will end up as a two point boundary value problem in the longitudinal direction. For the derived ODEs with constant coefficient of the two point boundary value problems, the displacement function is computed by integration instead of being given by traditional series. The numerical result of the present method will be very precise, almost up to the computer precision. Thus, the precise finite strip method can deal with various local effect problems which cannot be solved by many traditional methods. © 1998 Published by Elsevier Science Ltd. All rights reserved.
