Abstract

Abstract

An approach is presented for calculation of composite helicopter blade cross-sectional stiffnesses with finite element method on the basis of the two-dimensional linear model.The warping effect and deformation characteristics are incorporated in the formulation.As a result,a software was been developed,which consists of 3 nodes,4 nodes,6 nodes,8 nodes elements.The effectiveness of the program has been verified by means of comparison with NABSA's analytical results.
