...Abstract Abstract This chapter provides a detailed analysis of the cyclic stress-strain behavior of materials under uniaxial stress and strain cycling. It first considers the case of a stable material under constant-amplitude strain cycling then broadens the discussion to materials that harden...

... for a uniaxial case has been replaced by σ m,1 + σ m,2 + σ m,3 . The vertical axis is concerned only with amplitudes of cycling for each of the three directions. Thus, if the strain amplitude in the 1-direction is Δε 1 , and in the 2- and 3-directions, Δε 1 and Δε 1 , we have combined these three ranges...

... steel yields at an elastic tensile strain of about 0.2% at 4 K, although its elongation to fracture at that temperature may be as high as 30%. Conversely, a uniaxial boron–epoxy composite is elastic up to about 0.8% strain at 4 K. The corresponding limiting stress range is about 413 MPa (6 × 10 4 psi...
