SOLUTION: The tensile test method for a shaped steel according to an embodiment of the present invention includes a first step of preparing a test piece of the shaped steel and a camera, and two of the test pieces separated in the tensile direction. The second step of marking a place, ...
A standard uniaxial tensile test, which establishes the engineering stress-strain relationship, in general, provides the basic mechanical properties of steel required by a structural designer. Modern numerical analysis techniques used for analysis of large strain problems such as failure analysis of steel...
experimental research programme was carried out during the years 1994–2001 in the Laboratory of Steel Structures at Helsinki University of Technology in order to investigate the mechanical properties of several structural steels at elevated temperatures by using mainly the transient state tensile test ...

The mechanical properties of structural steel after cooling down have also been examined briefly and these test results are given in this report. The test results were used to determine the temperature dependencies of the mechanical properties, i.e. yield strength, modulus of elasticity and thermal...
Three techniques of strain measurement are compared in quantitative manner based on the calculation of mechanical properties (modulus of elasticity, yield strength, tensile strength, percentage elongation at maximum force) of structural steel. A statistical information was used for evaluating the results....
The weldability of Grade 80 and Grade 100 structural steel was examined. Welding tests were conducted to examine the effects of Gas Tungsten Arc Welding, Shielded Metal Arc Welding, and Gas Metal Arc Welding on both of the materials. Wel... SJ Hoskins - Masters Abstracts International, Volume...
