Experimental Study on Basic Mechanical Properties of Steel

  • AbstractIntroductionExperimentalResults and DiscussionConclusionsData AvailabilityAcknowledgmentsIn order to solve the problem of low strength and easy cracking of shotcrete in permanent support of tunnel single shell lining, the effects of steel fiber-reinforced siliceous on mechanical properties of wet shotcrete were investigated by the tests of compressive strength, splitting tensile strength, flexural strength, shear strength, and bending toughness. The strength and the cracking resistance mechanism of steel fiber-reinforced siliceous wet shotcrete were analyzed by the bending toughness evMechanical properties of cold-formed thick-walled steels Moreover, a prediction model of mechanical properties for the cold-formed thick-walled steels at elevated temperatures is proposed. Finally, coupon tests on the steels of the typical cold-formed thick-walled steel tube were finished to validate the proposed prediction model. 2. Experimental study 2.1 Pretreatment of test specimens Experimental study on mechanical properties of corroded Dec 28, 2017 · Experimental study on mechanical properties of corroded steel fibers under static and dynamic loading The results showed that the mechanical properties of the corroded steel fibers were strainrate dependent. With an increase in strain rate, the ultimate load increased, whereas, the strainrate effect decreased with an increase in the

    Four Q345c steel beams with corrugated webs were tested by Shimadzu 4890 fatigue testing machine, the static and fatigue mechanical characteristics of the high-strength beams were studied from the experimental point. During the experiment, firstly a static tests was carried out by four-point bending, confirmed the conclusions of the bending moment of beam with corrugated steel webs mainly Li, G.Q. and Chen, K.
