Introduction High-strength, light-weight metallic materials are required to improve safety and reduce transportation costs.
Ultrafine-grained metals whose grain size is less than 1 mm have attracted interest as high-strength materials.
A computational model predicting the yield surfaces of ultrafine-grained metals is desired in the field of materials science and engineering.

Long-Term Performance Research on Reinforced Concreted Beams with Pre-Stressed CFRP Plate Kefeng Zhou1,a, Yuzhi Li, Baojing Zhang1,b, 1School of Traffic and Transportation Engineering, Changsha University of Science and Technology Changsha, Hunan 410011, china a zkfsly780623@126.com,bsun870503@163.com Keywords: long-term test reinforce pre-stressed CFRP plate Abstract: With the continuous development of science and technology, the method of using the pre-stressed carbon fiber on the concrete structure, in particular on the bridge structure has become a research direction by the domestic and foreign scholars.
Sticking CFRP Laminate to reinforce the bridge technology for its high material corrosion resistance and effective craft has received favorably.
Experimental Program 1.1 Experimental materials What experiments of this article use is domestic carbon fiber plate.
(2) From this paper, the creep of domestic carbon fiber sheet under the long-term tension pre-stressed is so small that it can be definitely used as concrete flexural reinforcement materials.
