| Abstract: | This paper presents a mixed energy principle for beams and detailed solutions of statics, vibration, stability of beam and beams resting on elastic fundation have been developed. Mixed energy method not only can be extended to more fields for solving problems, but also yield higher precision of displacements and internal forces at same time, so peaple pay more attention to it. |
