Abstract

Abstract

In the light of matrix theory,the character of stress increment which causes the rotation of principal stress axes is analysed and the general stress increment is decomposed into two parts:coaxial part and rotational part.Based on these,the complex three dimension(3-D)problem involving the rotation of principal stress axes is simplified to the combination of the 3-D coaxial model and the theory about pure rotation of principal stress axes that is only around one principal stress axes.The difficulty of analysis is reduced significantly.The concrete calculating method of general 3-D problems is provided and other applications are also presented.
