Flutter analysis of rotating missile's variable cross-section empennage by differential quadrature method

摘要

Several years ago a new FRP reinforcement system was developed at Brno University of Technology. During the following years this system was refined to maximise its benefits and to lower the initial costs related to FRP materials. There was a special focus on anchoring and the development of a prestressed reinforcement length. There was a special focus on anchoring and the development of a pre-stressed reinforcement length. A large number of surfacing types were tested and the gained results were gathered and analysed using a bond-slip relationship. As most of today recommended calculations of the minimal anchoring length do not cover the influences of either the surfacing of the bar or the thickness of the concrete cover, a new extension was proposed. The equation was confirmed by a number of real-world tests.
