ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.
[1]: 58 For example, low-carbon steel generally exhibits a very linear stress–strain relationship up to a well-defined yield point. The linear portion of the curve is the elastic region, and the slope of this region is the modulus of elasticity or Young's modulus. Plastic flow initiates at the upper yield point and continues at the lower ...
A36 steel is a common structural steel alloy used in the United States. [1] The A36 (UNS K02600) standard was established by the ASTM International . The standard was published in 1960 and has been updated several times since. [ 2 ]
Young's modulus is the slope of the linear part of the stress–strain curve for a material under tension or compression.. Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise.
In solid mechanics and structural engineering, section modulus is a geometric property of a given cross-section used in the design of beams or flexural members.Other geometric properties used in design include: area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness.
Structural steel is a category of steel used for making construction materials in a variety of shapes. ... as well as an increase in ductility and elasticity.
Steel is equally strong in tension and compression. Steel is weak in fires, and must be protected in most buildings. Despite its high strength to weight ratio, steel buildings have as much thermal mass as similar concrete buildings. The elastic modulus of steel is approximately 205 GPa. Steel is very prone to corrosion .
Normal metals, ceramics and most crystals show linear elasticity and a smaller elastic range. Linear elastic deformation is governed by Hooke's law, which states: = where σ is the applied stress; E is a material constant called Young's modulus or elastic modulus; ε is the resulting strain.
