Where can I find the elastic modulus and Poisson’s ratio of steel?
Thread Content
Dear experts, where can I find the elastic modulus and Poisson’s ratio of steel? Is there some kind of standard or something?
Both the elastic modulus and Poisson’s ratio are inherent properties of a material, and both values can be determined experimentally. For pressure vessels, the elastic modulus can be found in Appendix B of GB/T 150.2; as for whether there is a standard for the Poisson’s ratio, I’m not sure – it seems to be around 0.3.
The elastic modulus is 150; for Poisson’s ratio, I usually start by assuming a value of 0.3 for calculations. When precision is required, calculate using the elastic modulus and shear modulus or refer to ASME. I usually just calculate it for fun; I haven’t really checked it much. I remember there being it on ASME
The elastic modulus of the corresponding materials is provided in Appendix B.13 of the national standard GB/T 150.2-2011, and it is also available in ASME Volume II-D; the Poisson’s ratio can be found in mechanics of materials
