The results show that: between 300℃ and 600℃, there is little influence on the elastic modulus and yield strength of the steel acted by prophase heating; there is about 20% reduce on the strength of steel made by the stress acted during the stage of heating.%为了对我国受火钢结构的承载...
Just another voice...the modulus of elasticity will be the same. If there was no permanent set, the deflection was elastic and will be the same with the different steel. Perhaps powder coating, at least this process, is not the right system to use. Upvote 0 Downvote Not open for furt...
However, the effect of pre-fatigue loading on the elastic modulus of Q345 structural steel is almost negligible.doi:10.1016/j.istruc.2023.104944Neng LuoSchool of Architecture, Chongqing University, Chongqing 400045, PR ChinaTiejun ZhouSchool of Architecture, Chongqing University, Chongqing 400045, PR ...
掳C, as well as air and water cooling methods, the residual elastic modulus, yield stress, ultimate tensile strength and ultimate strain were explored. Comparison of the residual mechanical properties of Q345FR steel with other structural steels confirmed their close relation to temperatures and ...
The results showed that the elastic modulus of bridge steel Q345 with corrosion rate of 0. 53%, 1. 22%, 2. 47%, 4. 12% and 4. 98% decreased by 26%, 2. 36%, 4. 04%, 7. 01% and 10. 93%, respectively, and the yield strength decreased by 0. 61%, 2...
However, due to the coldforming effects, the yield strength of the corner part of Q345 steel under elevated temperatures was much larger than that of the flat part. As a result, the current local buckling design specifications based on the reduced yield strength and elastic modulus of the ...
Under the same load testing temperatures, the differences in the elastic modulus reduction factors of Q345 CFS between the rising and falling temperature periods are within 0.16 to 0.057; meanwhile, the differences in the yield strength reduction factors between the rising and falling temperature ...
Furthermore, the four deformation stages, i.e., the elastic stage, the plastic modulus compatible deformation stage, uniform plastic deformation stage and non-uniform plastic deformation stage, of the laminated metal with parallel structure were firstly proposed under the modulating action of th...
The plastic modulus was analyzed with the different temperatures and the different strains in detail. The parameters of mechanical properties for steel Q345 were obtained for using in elastic-plasticity stress model.D.F.ChenL.HuangM.J.Long
