Defining Yield Stress and Failure Strength - failure criteria

Typical stress strain curves are actually just sequences of data points. Reliably determining second and/or third derivatives from such typical data sets is prohibitively difficult. So the situation appears to have reduced to the . common observation that “the …

stress-strain curves of the materials shown in Fig.2.4.. After repeated loading, these residual stresses are removed and the stress-strain curves become practically straight lines. For materials that do not have a well-defined yield point, yield stress is determined by

PLASTIC DEFORMATION BACKGROUND

Stress-Strain Curves Again we will use stress-strain curves to investigate the mechanical behavior of materials. Recall most of the properties aren't dependent on the specimen size, and the elastic modulus is the same whether we use a tensile test or a compression test to find it. Since the strain will be positive for tensile testing.

yield strain εy the first occurrence in a tensile test of strain increase without a stress increase NOTE 1 It is expressed as a dimensionless ratio, or as a percentage (%). NOTE 2 See Figure 1, curves b and c. NOTE 3 See Annex A (informative) for computer-controlled determination of the yield strain. 3.7.2 strain at break εb
