| Abstract: | In this paper,a method of strength and stiffness reliability analysis for bar plate structural systems,which can simulate the wing of the flyers,is presented.Based on the Mises's yield condition,the element safety margins about strength and stiffness of the plane stress element is derived.The correlation of failure modes between the strength and stiffness is discussed. |
