Stress Strain Curves
Stress Strain Curves
(OP)
Hi, where can I find stress strain curves for most of the alloy steels in one place, like SAE and AISI steels, tool steels (high strength) etc.? Are there any free internet sources available for them or would I have to buy a book? If the source would also include stress strain curves after some common material treatments like case hardening or gas nitriding etc.. that would be even better. Thanks. Sunny.

(1) Metals data including stress-strain and S-N curves. Select "Metals Handbook, MIL-HDBK-5H" at http://euler9.tripod.com/.
(2) Stainless steel stress-strain curves in App. A, p. 18, in http://www.civil.usyd.edu.au/publications/r811.pdf (0.50 MB).
(3) Metals database (?), http://fde.uwaterloo.ca/Fde/Materials/dindex.html.
(4) Steel sheet metal stress-strain curves (but I don't recognize the alloy names) in App. II in http://www.autosteel.org/TTD/TTD6_2001.PDF (2.3 MB). Huge download, most of which is NOT stress-strain curves.
(5) Polymer stress-strain curves, http://www.polyplastics.com/en/support/database/index_DB_2.html.

(6) Mild steel (ASTM A36M) stress-strain curve, stress in units of MPa as a function of strain, with Boolean coefficients, where "<=" means "less than or equal to," and ">=" means "greater than or equal to."
sign(x) = if(x<0,-1,1).
sigmaA36(x) = 0 + (|x|<=0.00125)(200000x) + (|x|>0.00125)(|x|<0.011)(sign(x))(250) + (|x|>=0.011)(|x|<0.232)(sign(x))(196.858 + 5399*|x| - 54375x^2 + 256000*|x|^3 - 503000x^4).

(8) Steel, stainless steel stress-strain curves. Select Section "B4.5.6" or "B4.5.5" at http://euler9.tripod.com/analysis/asm.html. The stress-strain curves are the "k = 1.0" curves appearing only in the charts labeled "Minimum Plastic Bending Curves" (two views, close up and far away), so page down until you find these charts. These plots are indexed and explained in the Sect. "B4.5.0" download file (on pp. 4, 5, and 35).
