Q460高强钢单调与反复加载性能试验研究
Experimental study on material properties of Q460 high strength steel under monotonic and cyclic loading
摘要
Abstract
By experimental study on the material properties of Q460 HSS under both monotonic and cyclic loading, Monotonie compressive loading and hysteretic curves of Q460 steel were obtained. The cyclic skeleton curves were compared with the existing research work. Results of the test show that, under monotonie loading, the average elongation rate of Q460C HSS plate with the thickness 11mm is 23. 7% , and the average yield to tensile strength ratio is 0. 847, while the average elongation rate of Q460 HSS plate with the thickness 21mm is 30. 4% , and the average yield to tensile strength ratio is 0. 792. The cyclic hardening property of Q345 is more obvious than that of Q460, since the increase of the strength of steel results in increased yield ratio while reduced strain hardening effect. By the hysteresis curve of Q460 obtained under cyclic loading, the stress-strain hysteresis model of Q460 HSS was proposed, which matched very well with experimental curves.关键词
