DATA SET 3
Stress-Strain Curves
This collection of stress-strain curves is representative of thebehavior of several cast alloys under tensile or compressive loads.The curves are arranged by alloy designation.
The curves are from the Atlas of Stress-Strain Curves, publishedby ASM International (Ref 1). The original source of and, whenavailable, some background on the data are indicated on eachgure.
Compressive tangent modulus curves, which represent the slopeof the compressive stress-strain curve, are given for some alloys.
The effects of cyclic loading are given on several curves. Thecyclic curves are constructed by connecting the points that repre-sent the tips of stabilized hysteresis loops. The curves given in-dicate the occurrence of cyclic hardening.
