May 30, 2020 · Both cold drawn SAE-AISI 1040 and normalized SAE-AISI 4140 are iron alloys. They have a very high 98% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown. For each property being compared, the top bar is cold Experimental and Numerical Validation of DIN standard Table 1 shows the result form the experiment using 4140 steel with Youngs Modulus of Elasticity (E) of 209 GPa, Poissons ratio (v) of 0.3, and Modulus of rigidity (G) of 80 GPa. The strain gage H 2 is the middle gage along the shaft axis. The reason for the axial normal strain is Materials Data BookYoungs modulus E = initial slope of t t curve = initial slope of n n curve. Yield stress y is the nominal stress at the limit of elasticity in a tensile test. Tensile strength ts is the nominal stress at maximum load in a tensile test.
Modulus of Rigidity - G - (Shear Modulus) is the coefficient of elasticity for a shearing force.It is defined as "the ratio of shear stress to the displacement per unit sample length (shear strain)" Modulus of Rigidity can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material.

Called Modulus of Rigidity in PanGlobal and Reeds, the shear modulus is defined (similarly as E) as ratio of shear stress to the shear strain. It is eed in GPa or psi and typical values are given in Textbook Appendix B. Typical values are lower than Youngs Modulus E, for instance ASTM A36 steel has E A36 = 207 GPa and G A36 = 83 GPa . eFunda:Properties of Alloy Steel AISI 3140Category :Steel:Class :Alloy steel:Type :Standard:Common Names :Nickel-chromium steel:Designations :Germany:DIN 1.5711 United Kingdom:B.S. 640 M 40 United Technical Information:4140 HT - SB Specialty Metals4140 HT Surface Hardening . 4140 HT is a medium carbon alloy steel heat treated to a . nominal hardness of 28-32 HRC. 4140 HT can also be surface hardened to increase wear resistance .
